The Nephilim were powerful, famous warriors described in Genesis 6:4, living in the violent years before Noah’s flood. Christians disagree about where they came from. Some believe fallen angels fathered them with human women, while others see them as the children of proud human rulers or of mixed marriages between godly and ungodly families. Either way, their story shows how far the world had fallen, and how firmly God stays in control.
What Does Genesis 6 Say About the Nephilim?
The Nephilim appear in just four short verses, tucked between Adam’s family tree and the story of Noah. Moses gives very few details, which is a big reason this passage has sparked so much curiosity over the centuries. What he does make clear is the setting: the human race was multiplying quickly, and so was its rebellion against God.
Genesis 6:1-4 Then the people began to multiply on the earth, and daughters were born to them. The sons of God saw the beautiful women and took any they wanted as their wives. Then the Lord said, “My Spirit will not put up with humans for such a long time, for they are only mortal flesh. In the future, their normal lifespan will be no more than 120 years.” In those days, and for some time after, giant Nephilites lived on the earth, for whenever the sons of God had intercourse with women, they gave birth to children who became the heroes and famous warriors of ancient times.
The Hebrew word nephilim may come from a verb meaning “to fall,” which is why some translate it “fallen ones,” though scholars still debate the root. The NLT calls them “giant Nephilites,” following the ancient Greek translation that called them giants. Notice that the text stresses their reputation more than their height. They were the celebrated strongmen of their day.
The very next verse tells us what God saw when he looked at that celebrated world: “everything they thought or imagined was consistently and totally evil” (Genesis 6:5). The Nephilim aren’t presented as heroes to admire. They’re part of the story of how evil spread through God’s good world, and part of the reason the flood came.
Who Were the “Sons of God” in Genesis 6?
To understand who the Nephilim were, you have to ask who their fathers were. The oldest view, common in Jewish writings before Jesus and among many early church leaders, says the “sons of God” were angels who rebelled against God. Elsewhere in the Old Testament, that phrase usually describes heavenly beings who stand before the Lord, part of what some call the divine council. Supporters of this view also point to a striking verse in the New Testament.
Jude 6 And I remind you of the angels who did not stay within the limits of authority God gave them but left the place where they belonged. God has kept them securely chained in prisons of darkness, waiting for the great day of judgment.
Jude follows this immediately with a reminder about the sexual immorality of Sodom and Gomorrah, which many readers take as a link to Genesis 6. A second view holds that the “sons of God” were the godly descendants of Seth who married into Cain’s ungodly line. People who hold this view often cite Jesus’ teaching that angels in heaven don’t marry (Matthew 22:30). A third view sees them as ancient kings who claimed divine status and took whatever women they wanted.
Each view has thoughtful defenders, and faithful Christians land in different places. That’s okay. No essential belief about God, Jesus, or salvation depends on settling this question.
Did the Nephilim Survive the Flood?
The Nephilim show up one more time, centuries later, when Moses sends twelve spies to scout the Promised Land. Ten of them come back terrified, and their report gets everyone’s attention.
Numbers 13:32-33 So they spread this bad report about the land among the Israelites: “The land we traveled through and explored will devour anyone who goes to live there. All the people we saw were huge. We even saw giants there, the descendants of Anak. Next to them we felt like grasshoppers, and that’s what they thought, too!”
Genesis 7:23 says the only people who survived the flood were Noah and his family, so how could Nephilim still be around? Pay attention to how Moses describes the spies’ words: a “bad report.” They were exaggerating to scare people, and “Nephilim” was likely the most frightening label they could reach for, much like calling someone a monster today. The descendants of Anak were real, tall people, but they weren’t a surviving hybrid race.
That’s a helpful guardrail for us. The Bible doesn’t support theories about secret giant bloodlines or ancient aliens in Scripture. Caleb and Joshua saw the same people and trusted that God was bigger.
Why Does the Story of the Nephilim Matter Today?
It’s easy to get lost in speculation, but Genesis includes the Nephilim for a reason. Whether the cause was rebellious angels or tyrant kings, people were grabbing power, fame, and pleasure on their own terms, and the result was a world God had to judge. That temptation hasn’t gone away. The story also reminds us that there really is an unseen spiritual world, and that evil powers are real but always limited.
The good news is that God didn’t let evil have the last word in Noah’s day, and he hasn’t let it win now. The cross settled that once and for all.
Colossians 2:15 In this way, he disarmed the spiritual rulers and authorities. He shamed them publicly by his victory over them on the cross.
Whatever the Nephilim were, they’re no threat to anyone who belongs to Jesus. Instead of fearing giants or fallen angels, you can rest in the One who has already defeated every power of darkness. Learn more about how much power the devil really has.
The Takeaway
So who were the Nephilim? They were the famous, mighty warriors of Genesis 6, born in a corrupt age before the flood, whether from fallen angels or powerful human rulers. Christians disagree on the details, but the story clearly shows sin’s devastation and God’s power to judge and rescue, power fully revealed in Jesus.
