Key passages
Historical and literary context
The flood story has parallels in Mesopotamian literature, above all the Epic of Gilgamesh and the Atrahasis epic, where the gods send a flood and one man is warned to build a boat; Genesis shares the shape and differs in the reason, human corruption rather than divine annoyance, and in the one God who grieves. A cubit is about 45 centimeters, so the ark was some 135 meters long, larger than any ship built before the nineteenth century. Gopher wood is unidentified. The "sons of God" have been read since antiquity as angels, as the line of Seth, or as rulers, and the Nephilim recur as giants in Numbers 13. Jesus and Peter both refer to the days of Noah.
How the chapter unfolds
Verses 1 to 4 tell of the sons of God and the daughters of men, the 120 years, and the Nephilim. Verses 5 to 8 give God's assessment of the human heart, his grief, his decision to blot out life, and Noah's favor. Verses 9 to 12 introduce Noah's account: his righteousness, his sons, and the corrupt, violent earth. Verses 13 to 21 are God's instructions: the end of all flesh, the ark and its measurements, the flood, the covenant, the animals, and the food. Verse 22 records Noah's complete obedience.
Why this chapter matters
Verse 5 is the Bible's starkest statement of human sinfulness and a foundation text for the doctrine of the fall, and verse 6, "the LORD regretted that He had made man," is its boldest statement that God feels. Noah walking with God, finding favor, and obeying to the letter became the model of faith in Hebrews 11 and of righteousness in a wicked age; the ark became, in Christian reading, a picture of baptism and of the church. "The days of Noah" are Jesus' image of a world caught unprepared. The first mention of "covenant" in the Bible is in verse 18.
Interpretive tension to watch
The identity of the sons of God and the Nephilim is the oldest puzzle in the chapter, and the church has never settled it. God's "regret" raises the question of whether an all-knowing God can change his mind, and readers answer with the language of accommodation, of genuine relationship, or of both. The destruction of every animal along with humanity troubles modern readers, and the flood's extent, global or regional, is debated among believers. Noah's "favor" in verse 8 comes before his righteousness in verse 9, which readers take as grace preceding goodness.
Questions for this chapter
- God is "grieved in His heart" over human evil. What does it mean that the judge of the world is also its mourner?
- Noah found favor before the text calls him righteous. Which comes first in your own story, being accepted or being good?
- "Noah did everything precisely as God had commanded him," for a flood no one could see. What does obedience look like when the reason is still invisible?

Genesis 6 is where the story of the world takes its darkest turn, and it is told with astonishing restraint. It opens with a strange episode, the sons of God taking human wives and the Nephilim, the giants of old, and God setting a limit of 120 years on a race that has gotten out of hand. Then the narrator gives God's view of things, and it is a sentence people have argued about ever since: the wickedness of humanity was great, and every inclination of the thoughts of the heart was only evil, all the time. What follows is not rage. The LORD regretted that he had made man, and it grieved him to his heart. The decision to wipe it all out is spoken by a God who is sorry. And then the hinge on which the whole Bible turns: but Noah found favor in the eyes of the LORD. Noah is righteous and blameless in his generation, and he walks with God, in a world the narrator describes three times as corrupt and full of violence. God tells him what is coming and what to build: a great chest of gopher wood, sealed with pitch, three hundred cubits long, three decks, one door, room for two of every creature and food for all of them. He also says a word that has not appeared in the Bible until now: covenant. I will establish my covenant with you. The chapter ends with one line about Noah that is the whole of his greatness. He did everything exactly as God commanded.
