The Nephilim appear by name in only two Bible verses: Genesis 6:4 and Numbers 13:33. That sounds straightforward, but the two references are not equally straightforward.
Genesis 6:4 places the Nephilim in the pre-Flood world alongside the “sons of God,” the “daughters of man,” and the “mighty men of old.” This is the Bible’s one uncontested narrative statement about their existence.
The second reference appears in Numbers 13:33, where ten frightened spies claim that they saw the Nephilim in Canaan. The statement comes at the climax of a fear-driven report intended to convince Israel that entering the land would be disastrous.
That does not necessarily mean every detail was invented. The Anakim, fortified cities, and powerful Canaanite peoples were real. But it does mean that Numbers 13:33 cannot be treated as an uncomplicated genealogy given directly by God.
This distinction matters because nearly every theory about post-Flood Nephilim depends on this disputed report. By connecting the Nephilim to the Anakim, the Anakim to the Rephaim, the Rephaim to Og, and Gath to Goliath, some interpreters construct a continuous Nephilim family tree.
The Bible itself never lays out that family tree.

Genesis 6:1–4: The Original Nephilim Reference
Genesis introduces the Nephilim in a short passage immediately before the account of Noah and the Flood:
“When man began to multiply on the face of the land and daughters were born to them, the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. Then the LORD said, ‘My Spirit shall not abide in man forever, for he is flesh: his days shall be 120 years.’
“The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown.”
Genesis 6:1–4, ESV
Four descriptions appear together:
- The sons of God
- The daughters of man
- The Nephilim
- The gibborim, or mighty men of old
The closest Old Testament parallels to “sons of God” appear in Job 1:6, 2:1, and 38:7, where the phrase refers to heavenly beings. This supports the ancient supernatural interpretation in which beings from the heavenly realm crossed a boundary by taking human women.
Other interpretations identify the sons of God as kings, tyrants, or descendants of Seth. These readings have a long history, but Genesis never explicitly calls the men Sethites, the women Cainites, or the sons of God human rulers.
The heavenly-being interpretation remains a strong reading within the passage’s ancient setting. Even so, Genesis does not call these beings Watchers, name their leaders, list their forbidden teachings, or explain the origin of demons. Those details come from later Jewish traditions, especially 1 Enoch.
Were the Nephilim Their Offspring?
The traditional interpretation identifies the Nephilim as the offspring of the sons of God and human women. That is also how 1 Enoch develops the story.
Genesis itself is less explicit. It says that the Nephilim were present during the period, then refers to children being born and identifies “these” as the mighty men of old.
The Nephilim, offspring, and gibborim are clearly associated. Whether the grammar identifies them as precisely the same group remains debated.
The word gibborim means mighty men, warriors, heroes, or champions. It is not a technical word for supernatural giants. Elsewhere, it describes Nimrod, accomplished warriors, and David’s fighting men.
The meaning of Nephilim is also uncertain. It may relate to the Hebrew root naphal, “to fall,” to fallen warriors, to those who cause others to fall, or possibly to an Aramaic term associated with giants.
The Septuagint translates Nephilim with the Greek gigantes. This helped establish the familiar translation “giants,” but the Greek term could evoke primeval power and rebellion rather than height alone.
Genesis never tells us exactly how tall the Nephilim were.
What Does “And Also Afterward” Mean?
Genesis 6:4 includes the puzzling statement:
“The Nephilim were on the earth in those days, and also afterward.”
This is frequently treated as proof that the Nephilim returned after the Flood. But the verse does not say “after the Flood.” At this point in Genesis 6, the Flood has not yet been announced.
“And also afterward” could refer to continued activity during the pre-Flood period. It could also function as a retrospective bridge connecting Genesis with later traditions about ancient warriors.
A post-Flood reference is possible, but the phrase does not explain how the Nephilim survived, returned, or produced a later bloodline.
Those explanations become necessary only if Numbers 13:33 is treated as an objective report of post-Flood Nephilim.
Numbers 13:33: Did the Spies Really See Nephilim?
Moses sent twelve spies to examine Canaan. Their initial report contained serious but realistic observations:
“We came to the land to which you sent us. It flows with milk and honey, and this is its fruit. However, the people who dwell in the land are strong, and the cities are fortified and very large. And besides, we saw the descendants of Anak there.”
Numbers 13:27–28, ESV
The land was fruitful. Its inhabitants were strong. Its cities were fortified. The descendants of Anak were present.
Caleb responded:
“Let us go up at once and occupy it, for we are well able to overcome it.”
Numbers 13:30, ESV
The other spies then intensified their report:
“We are not able to go up against the people, for they are stronger than we are.”
Numbers 13:31, ESV
Their language became increasingly dramatic:
“The land, through which we have gone to spy it out, is a land that devours its inhabitants, and all the people that we saw in it are of great height.”
Numbers 13:32, ESV
Finally, they invoked the Nephilim:
“And there we saw the Nephilim (the sons of Anak, who come from the Nephilim), and we seemed to ourselves like grasshoppers, and so we seemed to them.”
Numbers 13:33, ESV
The progression matters. The Nephilim do not appear in the initial geographical and military assessment. They appear at the climax of a report intended to make Israel afraid.
Numbers calls it a “bad” or “evil report.” The Hebrew word dibbah can describe a negative, damaging, or slanderous account. That does not prove that every observation was false. A damaging report can contain truth presented selectively or deceptively.
The spies may have combined:
- Accurate observations
- Exaggerated descriptions
- Fear-driven interpretations
- Legendary comparisons
- Faithless conclusions
The grasshopper comparison is plainly rhetorical. Likewise, when Deuteronomy describes the cities as “fortified up to heaven,” it does not mean their walls literally reached the sky.
The spies may have encountered unusually tall Anakim while using the legendary name Nephilim to make those enemies appear unbeatable.
Moses Retells the Story
Deuteronomy 1 preserves Moses’ later account:
“Our brothers have made our hearts melt, saying, ‘The people are greater and taller than we. The cities are great and fortified up to heaven. And besides, we have seen the sons of the Anakim there.’”
Deuteronomy 1:28, ESV
Moses retains the tall people, fortified cities, Anakim, and resulting fear. He does not repeat the claim that the Anakim descended from Nephilim.
This omission does not prove that the Numbers statement was fabricated. Biblical retellings often select and compress details. Nevertheless, it shows that Moses could explain Israel’s fear without repeating the most sensational element of the report.
The safest conclusion is that the spies may have drawn upon an existing tradition connecting the Anakim with the legendary Nephilim. But Numbers 13:33 does not give us a secure biological genealogy extending from Genesis 6 through the Flood and into Canaan.
Are the Anakim and Rephaim Nephilim?
The Anakim were real inhabitants of Canaan. Deuteronomy calls them “a people great and tall,” while Joshua describes their removal from much of the land:
“There was none of the Anakim left in the land of the people of Israel. Only in Gaza, in Gath, and in Ashdod did some remain.”
Joshua 11:22, ESV
Deuteronomy also connects the Anakim with a wider category called the Rephaim.
The Emim are described this way:
“The Emim formerly lived there, a people great and many, and tall as the Anakim. Like the Anakim they are also counted as Rephaim, but the Moabites call them Emim.”
Deuteronomy 2:10–11, ESV
The Zamzummim are described similarly:
“It is also counted as a land of Rephaim. Rephaim formerly lived there, but the Ammonites call them Zamzummim, a people great and many, and tall as the Anakim.”
Deuteronomy 2:20–21, ESV
These relationships are explicit. The Anakim, Emim, and Zamzummim belong to or are compared within the Rephaim tradition.
What Scripture never explicitly says is that every Rephaim was a Nephilim.
The larger theory works like this:
- Numbers 13 associates the Anakim with Nephilim.
- Deuteronomy associates the Anakim with Rephaim.
- Og was a Rephaim.
- Some Anakim remained in Gath.
- Goliath came from Gath.
- Therefore, Og and Goliath were Nephilim.
Each step contains a biblical connection, but the final conclusion is never stated. The farther the chain extends, the more it depends upon treating the spies’ disputed claim as a literal genealogy.
Were Og and Goliath Nephilim?
Og was king of Bashan and a remnant of the Rephaim:
“For only Og the king of Bashan was left of the remnant of the Rephaim. Behold, his bed was a bed of iron. Is it not in Rabbah of the Ammonites? Nine cubits was its length, and four cubits its breadth, according to the common cubit.”
Deuteronomy 3:11, ESV
Og’s bed or resting place measured approximately 13.5 feet long and 6 feet wide. This contributed to his imposing reputation, but the text gives the dimensions of an object, not Og’s body.
It may have been an unusually large bed, ceremonial couch, funerary object, or monumental structure. We cannot simply convert its length into Og’s height.
Goliath presents a different question:
“And there came out from the camp of the Philistines a champion named Goliath of Gath.”
1 Samuel 17:4, ESV
The Masoretic Text describes Goliath as six cubits and a span, approximately 9 feet 9 inches. The Dead Sea Scroll manuscript 4QSamᵃ, important Greek witnesses, and Josephus preserve four cubits and a span, approximately 6 feet 9 inches.
Either measurement presents an imposing warrior, but 1 Samuel never calls Goliath a Nephilim.
His connection is indirect. He came from Gath, where some Anakim had remained. Later warriors from Gath are associated with Rapha or “the giant,” wording possibly connected with the Rephaim tradition.
This makes Goliath relevant to the Bible’s larger giant-warrior tradition. It does not establish a biological line back to Genesis 6. For the full comparison, see Was Goliath a Nephilim? A Biblical Family Tree.
Does Ezekiel 32:27 Mention the Nephilim?
Ezekiel 32 pictures defeated nations and warriors in Sheol:
“And they do not lie with the mighty, the fallen from among the uncircumcised, who went down to Sheol with their weapons of war, whose swords were laid under their heads, and whose iniquities are upon their bones; for the terror of the mighty men was in the land of the living.”
Ezekiel 32:27, based on the Masoretic Text
The Hebrew phrase gibborim nophelim, “mighty fallen ones” or “fallen warriors,” resembles both gibborim and Nephilim in Genesis 6:4.
The Greek Septuagint strengthens the connection by describing “the giants who fell of old.” Ronald Hendel has proposed reading the verse as “the warriors, the Nephilim of old.” Brian Doak retains the normal “fallen warriors” reading but still recognizes an allusion to the Nephilim tradition.
Ezekiel 32:27 is therefore best classified as a possible literary echo, not an uncontested third use of the name.
Even if Ezekiel intentionally recalls the Nephilim, these figures are dead in Sheol. The passage does not describe a living Nephilim population or explain the ancestry of Og, Goliath, or the Canaanite clans.
Did the Nephilim Return After the Flood?
Four explanations are commonly proposed:
| Theory | Main difficulty |
|---|---|
| Nephilim survived outside the ark | Scripture says nothing about such survival |
| Nephilim ancestry passed through Noah’s family | No family member or mechanism is identified |
| A second angelic incursion produced new Nephilim | Neither Scripture nor the major Second Temple accounts describes one |
| Later warriors were compared with legendary Nephilim | Fits the rhetoric of Numbers 13 but remains an interpretation |
Importantly, neither 1 Enoch nor Jubilees describes a second post-Flood angelic incursion. Their continuing problem after the Flood involves evil spirits, not another generation of physical giants.
A more restrained possibility is that Nephilim became a legendary designation for terrifying ancient warriors. The spies encountered the genuinely formidable Anakim and described them using the most frightening comparison available.
This would explain why the name appears in their report but disappears from later accounts of the Anakim and Rephaim.
Was Canaan Conquered to Eliminate Nephilim?
Some interpretations turn the conquest of Canaan into a biological “seed war.” On this theory, Nephilim ancestry contaminated the Canaanites, and Israel was commanded to eliminate a hybrid bloodline.
Scripture gives other reasons:
- God’s covenant promise to Abraham
- The accumulated iniquity of the Amorites
- Judgment against Canaanite practices
- God’s faithfulness rather than Israel’s righteousness
- The establishment of Israel in the promised land
The Bible never states that Canaanite genetics were the reason for judgment.
There may still be a broader theological pattern. Rebellious powers oppose God, terrifying warriors defy his people, and God defeats proud enemies through apparently weaker servants. David’s victory over Goliath fits that pattern.
But a theological pattern is not the same as a biological genealogy.
Likewise, Genesis 6:9 describes Noah as righteous and “blameless in his generation.” The Hebrew tamim naturally concerns integrity or completeness. The passage does not say that Noah possessed genetically uncontaminated DNA.
What First Enoch, Jude, and Second Peter Add
First Enoch expands Genesis 6 into the Watcher story. It names the angels, places their descent at Mount Hermon, describes their forbidden teachings, and explicitly identifies their offspring as destructive giants.
It also teaches that the spirits of the dead giants became evil spirits:
“The spirits of the giants shall be like clouds, which shall oppress, corrupt, fall, contend, and bruise upon earth.”
1 Enoch 15, traditional translation
This is an important ancient interpretation, but Genesis never states that demons are the spirits of dead Nephilim.
Jude refers to angels who abandoned their proper dwelling:
“And the angels who did not stay within their own position of authority, but left their proper dwelling, he has kept in eternal chains under gloomy darkness until the judgment of the great day.”
Jude 6, ESV
Second Peter describes a similar judgment:
“For if God did not spare angels when they sinned, but cast them into hell and committed them to chains of gloomy darkness to be kept until the judgment.”
2 Peter 2:4, ESV
These passages show that Watcher-like traditions were familiar to New Testament writers. Jude also quotes an Enochic prophecy in verses 14–15.
But neither Jude nor 2 Peter:
- Names the Nephilim
- Calls the Anakim or Goliath Nephilim
- Describes a second angelic incursion
- States that demons are dead Nephilim spirits
- Declares every part of 1 Enoch inspired
Later sources help us understand how ancient readers interpreted Genesis. They should not be silently imported into the biblical passage and presented as though every detail appears there.
What We Can Say, and What We Cannot Say
The evidence supports
- The Nephilim existed in the pre-Flood setting of Genesis 6.
- The sons of God are plausibly understood as heavenly beings.
- The spies claimed to see Nephilim in Canaan.
- The Anakim and Rephaim were remembered as formidable peoples.
- Og belonged to the Rephaim tradition.
- Goliath was an unusually imposing warrior from Gath.
- Ezekiel may echo the ancient Nephilim tradition.
- First Enoch significantly shaped later interpretation of Genesis 6.
The evidence does not clearly establish
- The exact biology or height of the Nephilim
- How Nephilim survived or returned after the Flood
- A second angelic incursion
- That every Anakim or Rephaim was a Nephilim
- That Og or Goliath possessed Nephilim ancestry
- That Canaan was conquered to eliminate hybrid genetics
- That Noah was selected for genetic purity
- That the Bible identifies demons as spirits of dead Nephilim
Conclusion: Two References and a Much Larger Tradition
The Nephilim appear by name in only two Bible verses.
Genesis 6:4 gives the clear pre-Flood reference. Numbers 13:33 records a post-Flood claim, but that claim comes from frightened spies escalating a report intended to discourage Israel.
The rest of Scripture preserves a wider network of giant-warrior traditions. The Anakim were real and intimidating. The Rephaim included ancient peoples and rulers such as Og. Gath produced Goliath and other formidable warriors. Ezekiel may deliberately recall the fallen warriors of Genesis 6.
These relationships justify studying the passages together. They do not create an explicit Nephilim family tree.
The result is less sensational than many online explanations, but more faithful to the evidence. We do not need to dismiss the supernatural reading of Genesis 6. We also do not need to turn every ancient warrior, monumental bed, or underworld reference into proof of a surviving hybrid bloodline.
The Bible gives us one clear pre-Flood reference, one disputed post-Flood claim, several possible echoes, and a long history of interpretation.
Keeping those categories distinct allows the biblical text to remain as clear, and as mysterious, as it actually is.
