So, it seems you’re curious about Nephilim in the Bible. You very easily could have ended up on a site with not-so-reliable information (we’re looking at you, Wikipedia!). But, here you are! And you’ll be better off for it because you won’t just learn reliable information on the Nephilim. We’re also going to teach you how to do the research yourself.

Pick Reliable Resources for Researching Nephilim & Other Topics in the Bible

First, we need to pick reliable resources for researching Nephilim in the Bible. We will want quality information, from good sources. Here are some easy tips to get started:

Tips for telling a good source from a bad source

  • Research the author — are they credible?
  • Look at their citations — do they have any? Where did they get their information?
  • Beware of overly dramatic language.
  • Does the website and/or publisher appear professional and recommended by other professionals?

Primary Sources on Nephilim

Before jumping into secondary sources, let’s take a look at what the Bible says about Nephilim. This should be the first place you look. However, it can be tricky finding every reference without help. Thankfully, there are great tools that can help you accomplish this step in a few minutes. 

Use Olive Tree’s Search Feature

Quickly search by tapping the magnifying glass icon.

We’ve worked hard to make sure our search feature gives all the results you’re looking for. In fact, we could get into the knitty gritty of searching for specific variations of phrases… but that’s a different post. Right now, let’s see how many verses we can find containing “Nephilim.”

Genesis 6:1-8, NIV

“When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. Then the Lord said, ‘My Spirit will not contend with humans forever, for they are mortal; their days will be a hundred and twenty years.’

The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.

The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. The Lord regretted that he had made human beings on the earth, and his heart was deeply troubled. So the Lord said, ‘I will wipe from the face of the earth the human race I have created—and with them the animals, the birds and the creatures that move along the ground—for I regret that I have made them.’ But Noah found favor in the eyes of the Lord.” 

Numbers 13:31-13, NIV

“But the men who had gone up with him said, ‘We can’t attack those people; they are stronger than we are.’ And they spread among the Israelites a bad report about the land they had explored. They said, ‘The land we explored devours those living in it. All the people we saw there are of great size. We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.’”

Always read verses in context!

Strong’s Tagged Bibles

The Hebrew word for nephilim in a Strong's Tagged Bible

The search feature only looks for the word in the language you’ve searched in. In our case, we used English. But you can also search for the word in its original language, Hebrew, with a Strong’s Tagged Bible.

First, tap on any word you want to look up. Right away, a definition will appear. Sometimes, words in the original language can have a different meaning than we expect! Dictionary entries like this one will make sure you are on the right track.

Second, search the Strong’s number throughout the Bible (peep some of those in-depth search options we mentioned previously). You may or may not find new instances of the word being used. However, the verses we found in our first search really are the only ones that reference “Nephilim.” 

Secondary Sources on Nephilim

Next, it can be good to look at secondary sources. These resources are created by people who have spent their lives academically studying the Bible. 

Start with academic resources that use simple sentences and quick blurbs. You’ll find notes like these in study Bibles. If you want more information, you can look into commentaries, finding one that fits your reading level and covers the topics you want. 

Using Study Bibles to Learn about Nephilim

NIV Study Bible

We’ve looked into a few popular study Bibles to find basic information on Nephilim. Here are some quotes we found.

Nephilim. People of great size and strength. (see Nu 13:31-33; Dt 1:28 and note). The Hebrew word means “fallen ones.” They were viewed by people as “the heroes of old, men of reknown,” but in God’s eyes they were sinners (“fallen ones”) ripe for judgment.NIV Study Bible Notes

NIV Study Bible Notes on Nephilim

Did you catch the extra verse reference? Our search results didn’t pull up Deuteronomy 1:28, but the NIV Study Bible Notes said this verse references Nephilim. Let’s read it:

“Where can we go? Our brothers have made our hearts melt in fear. They say, ‘The people are stronger and taller than we are; the cities are large, with walls up to the sky. We even saw the Anakites there.” — Dt 1:28

We tapped on the verse reference in the study Bible notes to read it!

Then, the NIV Study Bible contains another note on this verse. 

Anakites. Earlier inhabitants of Canaan, described as giants (see Dt 2:10, 21; 9:2; Nu 13:32-33).

We’ve already read the verse from Numbers, but let’s look at the other verses mentioned here for further background information.

“The Emites used to live there—a people strong and numerous, and as tall as the Anakites.” — Dt 2:10

“That too was considered a land of the Rephaites, who used to live there; but the Ammonites called them Zamzummites. They were a people strong and numerous, and as tall as the Anakites. The Lord destroyed them from before the Ammonites, who drove them out and settled in their place.” — Dt 2:20-21

“The people are strong and tall—Anakites! You know about them and have heard it said: ‘Who can stand up against the Anakites?’” — Dt 9:2

Note on the Anakites in the NIV Study Bible Notes

One Last Piece of Information from the NIV Study Bible

The phrase “sons of God” here (in Genesis 6:2) is interpreted to refer either to angels or to human beings.

Sons of God as Angels

In such places as Job 1:6; 2:1 it refers to angels, and probably also in Ps 29:1 (where it is translated “heavenly beings”). Some interpreters also appeal to Jude 6–7 (as well as to Jewish literature) in referring the phrase here to angels.

Others, however, maintain that intermarriage and cohabitation between angels and human beings, though commonly mentioned in ancient mythologies, are surely excluded by the very nature of the created order (see ch. 1; Lk 20:34–36). Elsewhere, expressions equivalent to “sons of God” often refer to human beings, though in contexts quite different from the present one (see Dt 14:1; 32:5; Ps 73:15; Isa 43:6; Hos 1:10; 11:1; Lk 3:38; 1Jn 3:1–2, 10). 

Sons of God as Sethites

“Sons of God” (vv. 2, 4) possibly refers to godly men, and “the daughters” to sinful women (significantly, they are not called “daughters of God”), probably from the wicked line of Cain. If so, the context suggests that vv. 1–2 describe the intermarriage of the Sethites (“sons of God”) of ch. 5 with the Cainites (“the daughters”) of ch. 4, indicating a breakdown in the separation of the two groups.

Sons of God as Corrupt Rulers

Another plausible suggestion is that the “sons of God” refers to royal figures (kings were closely associated with gods in the ancient Near East) who proudly perpetuated and aggravated the corrupt lifestyle of Lamech, son of Cain (virtually a royal figure), and established for themselves royal harems.

A long note from the NIV Study Bible on Genesis 6:2, the sons of God.

What Have We Learned So Far?

  • The Nephilim are tall
  • The Nephilim are strong
  • There were a lot of Nephilim
  • The Anakites descend from the Nephilim
  • The Anakties (and then perhaps the Nephilim?) are from Canaan
  • The Emites may also be Nephilim
  • The Rephaites may also be Nephilim
  • The Nephilim were well known
  • The Nephilim may have been a result of the intermarriage of the “sons of God” and “the daughters,” or perhaps they were also simply known as heroes of old
  • There are three different ideas on who the sons of God and daughters were:
    • Angels and human women
      • “Sons of God” mean angels elsewhere in the Bible
      • However, this is against the natural order of things
    • Intermarriage between the Sethites (sons) and the wicked Cainites (daughters)
    • Sons of God were royal, corrupt figures

Using Commentaries to Learn About Nephilim

NIV Application Commentary

The NIV Application Commentary “so we will be brief.” lol not but that’s ok, because we want info!

First the author covers the three views we’ve mentioned above. He goes much more in-depth.

Some fun facts we found:

  • Sons of God as angelic beings was the view held unanimously until the second century
  • Then the intermarriage concept rose to popularity through Augustine’s City of God and soon became the Christian interpretation – until the nineteenth century

Next, the author goes really in-depth. We wish we could share everything here with you, but it would be too much.

Seriously, check out just how much information NIVAC had on this topic!

So, here’s a summary:

The angelic view has been around a long time. If we want to consider the Sethite or rulers views, we need to see if there is any reason the angelic view doesn’t work. Here are three contentions:

  1. Cohabitation between angels and humans has no immediately obvious connection with the purposes of Genesis;
  2. an angelic intrusion is considered out of place in the sequence of episodes recounting the advance of human sin; and
  3. the mythological tone is at odds with life in the real world as we know it, though in the end our interest is in the world as the Israelites knew it.

It makes much more sense (in the literary, cultural, and theological context) for “sons of God” to point more to “Sethites” or “rulers.”

Then, the author offers some reasons for why the “Sethites” view is flawed:

  • It ignores the question of the existence of other lines of descent from Adam and Eve
  • assumes that the lines of Cain and Seth remained separate for millennia
  • extrapolates from the statements about Enoch and Lamech that the entire line of Seth was godly and the entire line of Cain was wicked
  • it is much more difficult to see the phrase “daughters of men” in theological terms referring to females of the line of Cain
  • Why should “daughters of men” be used to describe wicked people?
  • it is difficult to extrapolate the warnings against elect Israel intermarrying and apply them to a group (Sethites) that has not been designated elect

Lastly, he offers even some critiques of the “rulers” viewpoint. Essentially, it is difficult to nail down the offense. Is the problem that the rulers were practicing polygamy or being promiscuous? History shows us that perhaps both are the answer. Although the passage uses the word “married,” this could be in reference to “right of the first night” — “the local authority imposes his will on his people by demanding and exercising the right to spend the first night with any woman who is being married.”

If this exercise of the right of the first night is the offense, the offenders are people in authority. This theme fits well with the progression of offenses in these early chapters: individuals (Adam and Eve) → family (Cain) → society leaders (sons of God) → everyone (Flood).

Learning About Nephilim with Other Resources

Lastly, let’s look at a couple resources that aren’t your standard study Bible or commentary.

Ancient Christian Commentary on Scripture 

This “commentary” is truly one-of-a-kind. It pulls together all the comments made by church fathers and organizes them by sections of Scripture. That way, you can quickly refer to a handful of church father’s notes while reading the Bible. Without this tool, you’d be stuck researching every church father’s words on a particular passage.

What a time saver!

One Final Summary: Who Were the Nephilim in the Bible?

Alright! We we went really in-depth, but here is one, birds-eye view of the question we aimed to answer:

Who were the Nephilim in the Bible?

The Nephilim (Hebrew: נְפִילִים, nefilim) were the offspring of the “sons of God” and “daughters of men” found in Genesis 6. Their height terrified surrounding communities. There are three beliefs concerning the origin on the Nephilim: 1. The Sons of God were angels, mating with human women. 2. The Sons of God were Sethites, mating with foreign Canaanite women. 3. The Sons of God were evil rulers, overtaking women in their city. John MacArthur Intro to the Gospels

What Will You Research Next?

Wow! We did it. Maybe this article was much longer than you intended. But if you stuck through it, congrats! You took the time to dig into a subject in the Bible that is often summarized in one or two sentences.

Now that you’ve learned about some important Bible study tools and tips, what will you study next?

We’d love to hear your ideas in the comments below. Maybe it will inspire a new post! Also, you can look through our currently discounted Bible study tools to snag quality information for cheap.


  1. Thank you so much for sharing and summarizing these to us. I added these books to my wishlist and I will buy it soon. God bless you all!

    • In the 3 points which are mentioned in the summary regarding the identity of the Nephilim – the second and the third dont account for the giant size of the Nephilim

  2. Terence Westoby

    The book of Enoch 7.1 These [watchers] and all the others with them took women for themselves from among all whom they chose. And
    they began to go in to them, and to defile themselves with them until the flood, and to teach them sorcery and and spellbinding, and to reveal to them the cutting of roots and herbs. 2 And the women became pregnant by them and bore to them three kinds. First great giants. And the giants begot Nephilim, and to the Nephilim were born Elioud. And they were growing in accordance with their greatness.

    This is a book made reference to in the Bible, and it makes clear (reading wider than the quoted text) that this was an angelic-human relationship. Hence the extraordinary size of the result. I wonder if the book of Enoch could be part of your available resources? My reference is a downloadable pdf file.

      Email me I scanned quickly yet held on your place in comments ..

  3. I agree entirely with Terence Westoby about the Book of Enoch. It is an essential reference for understanding some of the very obscure passages in Scripture. One example is the ‘spirits in prison’ referred to in 1Pet.3:18-20, and an exegesis of this passage which draws on the Book of Enoch can be found in: France, R T Exegesis in practice: two examples, pp264-281 In: New Testament Interpretation, Essays on Principles and Methods, ed. I Howard Marshall (Paternoster, 1977)

    I think that I remember reading that the Book of Enoch was seriously considered for inclusion in the Canon of Scripture.

    • Crystal

      What do you know about or what’s your knowledge and or wudom of the “prison” mentioned…
      Been there
      Is this the with 400 yrs between 1 and 2?

  4. In reference to marriage…The Lord seems to imply in Matthew 22 and Mark 12 that angels don’t marry…how does this fit with the “sons of God” being angels who “took wives,” Genesis 6?

  5. As the concept of “fallen ones or Nephilim ” is concerned note that to fall a person has to first be be “above”. To be fallen means “fallen from a condition of exaltation or a higher place”.

    All of the penalties in Gen 6 are toward man and not angels. Since God is just this would suggest that angels were not involved in the rebellion.

    This “falling” can be similar to – 2Th 2:3 let no man beguile you in any wise: for it will not be, except the falling away come first, and the man of sin be revealed, the son of perdition, (ASV)

    Falling away can be a term used to describe a person who is “falling” into sin.

    The result of the union of the Son’s of God and the Daughter of “Men”, are referred to as “Men” (Strong’s 582), and not angels. in Gen 6:4.

    Quote from – The father will determine the sex of the child. This is because, during sexual reproduction, each parent will donate one gamete. The female gamete will always have an X chromosome, while the male gamete can contain an X or a Y chromosome. The sex chromosome of the father’s gamete will determine the sex of the offspring. End Quote

    The Hebrew word for men as in the phrase “Daughters of men” in Gen 6:2 is “Adam” (Strong’s 0120) .

    After the union of the Sons of God and the daughters of men (Strong’s 120 -Adam) the offspring in Gen 6:4 are “men” as well, however the Hebrew word “enowsh” (Strong’s 582) is used , and this word identifies a less dignified description of men.

    Gen 6:1 NOTE “when men began to multiply…,and daughters were born to them(men). In verse 2 …sons of God took Wives for themselves. They married this women they did it by choice. Verse 3 GOD saw this things.. He then passed Judgement NOTE He said, “…he(man) also is flesh[that means the sons of God are Fleshly beings and the Nephilims too but in man is the spirit of GOD. The daughters bore children to the sons of GOD. this children were not Nephilims but renowned men.
    The account in numbers 13:33 is quit different from the Gen 6:4. The sons of Anak and not the sons of nephilims. Anak is a man while the other are nephilims and perhaps ancient Hebrew writings always refer to the direct father of the said person or children. Nephilim is a type of being while Anak is a human being a man. Now the nephilims all died in the flood and only Noah and his wife and three of his sons and their wives survived and the animals that went into the ark in twos.

  9. Michael J Borden

    I found this information regarding what a Nephilim really is to be fascinating. The only fact I knew about them was they were the result of a union between an Angel of God and a human being. Now I understand what Goliath was. My understanding is that all of Gods Angel’s (The different castes) actually have no definitive form or sexual identity because they are pure divine beings of light. Angel’s of God assume a form that when appearing before humans, we would be comfortable with their divine presence. The question I have is that if they are neither male or female, how were Angel’s able to reproduce with humas? I ask this question because I have a fascination with the Archangels of God. My mother named me after Saint Michael the Archangel and when I did my confirmation I chose to be called Michael John Raphael Borden (After Saint Raphael the Archangel). I welcome any opinions from anyone who wishes to answer my question. Thanks everyone for taking the time to read my response to this well written article.

    • I was told when i was young that angels were both male and female rather than neither male nor female. No idea where that came from, i was too young to ask many questions at the time. But I’d be interested to hear if anyone had info on that idea or where it came from

  10. Amir Tsarfati did a podcast on this. If you download the behold Israel app you can find them. I think It was titled: the great collision. It’s been almost 2 years since I listened To that, but it was very interesting.

  11. They were falling ones the angels that followed Lucifer. They were kicked out of heaven. They live in the second heaven and on the earth. They mated with women and had half god half human baby’s that grew to be giant’s because they were half god and half human. The taught the humans bad things. God destroyed them but one of Noah’s sons wives carried the blood line of neph they had nimrod . God destroyed man and put the fallen angels in hell in chains. They were the giants in the promise land with the huge size fruit they have lower gods power not the God of heaven and earth. What IV learned about this biblical story so far.

  12. Sorry, the Anakims could not be descendent of the Nephilim. Scripture clearly teaches that only eight survived from the flood – that would be Noah and his family.

  13. What if they were referring to the Kabbalistic view of Lillith? What would her offspring be? Just something that popped into my head.
    Also since Genesis is from the Old Testament and the Israelites, it might mean something different in translation because the words came from different languages as the different civilizations rose and fell. The book of Enoch describes at least three times that I found: bin elohim, or in the old Ugarutic (spelling?) “Bn ilm”. This has been found to be from the Ugaric and meant “of (as in begat) the Gods (plural),” and is masculine, giving us “sons of.” This also might not have meant that the sons were born directly of Gods. It might mean they were holy and simply men of Godly ways. As this theory goes, it poses the question that perhaps the daughters were simply of men and did not know God, only going about life without belief or faith. It definitely is worth exploring since it doesn’t point the finger at either group being sinful from the get-go. It also gives a relationship to modern issues when people of two faiths marry and don’t make any agreement on their child’s faith upbringing. Just like deciding to join bank accounts or not, it’s a topic that needs to be addressed in a marriage.
    What if these unions were males of faith to females who had not been brought up in belief, and they just decided to give up faith altogether? This makes sense in a reality – based theory. Why their offspring would be large might just be a charateristic of that tribe of peoples plus a land of plenty, ensuring good nutrition. Smilar to how there are stories of the Amazons?
    This is definitely a great conversation/research topic & has me thinking!
