Noah, the Ark, and the Flood

Genesis — Genesis 6:9-7:24 GEN_007

NET Bible Text

6:9 This is the account of Noah. Noah was a godly man; he was blameless among his contemporaries. He walked with God. 6:10 Noah had three sons: Shem, Ham, and Japheth. 6:11 The earth was ruined in the sight of God; the earth was filled with violence. 6:12 God saw the earth, and indeed it was ruined, for all living creatures on the earth were sinful. 6:13 So God said to Noah, “I have decided that all living creatures must die, for the earth is filled with violence because of them. Now I am about to destroy them and the earth. 6:14 Make for yourself an ark of cypress wood. Make rooms in the ark, and cover it with pitch inside and out. 6:15 This is how you should make it: The ark is to be 450 feet long, 75 feet wide, and 45 feet high. 6:16 Make a roof for the ark and finish it, leaving 18 inches from the top. Put a door in the side of the ark, and make lower, middle, and upper decks. 6:17 I am about to bring floodwaters on the earth to destroy from under the sky all the living creatures that have the breath of life in them. Everything that is on the earth will die, 6:18 but I will confirm my covenant with you. You will enter the ark – you, your sons, your wife, and your sons’ wives with you. 6:19 You must bring into the ark two of every kind of living creature from all flesh, male and female, to keep them alive with you. 6:20 Of the birds after their kinds, and of the cattle after their kinds, and of every creeping thing of the ground after its kind, two of every kind will come to you so you can keep them alive. 6:21 And you must take for yourself every kind of food that is eaten, and gather it together. It will be food for you and for them. 6:22 And Noah did all that God commanded him – he did indeed. 7:1 The Lord said to Noah, “Come into the ark, you and all your household, for I consider you godly among this generation. 7:2 You must take with you seven of every kind of clean animal, the male and its mate, two of every kind of unclean animal, the male and its mate, 7:3 and also seven of every kind of bird in the sky, male and female, to preserve their offspring on the face of the earth. 7:4 For in seven days I will cause it to rain on the earth for forty days and forty nights, and I will wipe from the face of the ground every living thing that I have made.” 7:5 And Noah did all that the Lord commanded him. 7:6 Noah was 600 years old when the floodwaters engulfed the earth. 7:7 Noah entered the ark along with his sons, his wife, and his sons’ wives because of the floodwaters. 7:8 Pairs of clean animals, of unclean animals, of birds, and of everything that creeps along the ground, 7:9 male and female, came into the ark to Noah, just as God had commanded him. 7:10 And after seven days the floodwaters engulfed the earth. 7:11 In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month – on that day all the fountains of the great deep burst open and the floodgates of the heavens were opened. 7:12 And the rain fell on the earth forty days and forty nights. 7:13 On that very day Noah entered the ark, accompanied by his sons Shem, Ham, and Japheth, along with his wife and his sons’ three wives. 7:14 They entered, along with every living creature after its kind, every animal after its kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, everything with wings. 7:15 Pairs of all creatures that have the breath of life came into the ark to Noah. 7:16 Those that entered were male and female, just as God commanded him. Then the Lord shut him in. 7:17 The flood engulfed the earth for forty days. As the waters increased, they lifted the ark and raised it above the earth. 7:18 The waters completely overwhelmed the earth, and the ark floated on the surface of the waters. 7:19 The waters completely inundated the earth so that even all the high mountains under the entire sky were covered. 7:20 The waters rose more than twenty feet above the mountains. 7:21 And all living things that moved on the earth died, including the birds, domestic animals, wild animals, all the creatures that swarm over the earth, and all humankind. 7:22 Everything on dry land that had the breath of life in its nostrils died. 7:23 So the Lord destroyed every living thing that was on the surface of the ground, including people, animals, creatures that creep along the ground, and birds of the sky. They were wiped off the earth. Only Noah and those who were with him in the ark survived. 7:24 The waters prevailed over the earth for 150 days.

Simple Summary

God saw a violent and ruined world. He judged it with the flood, but he preserved Noah and his household through the ark he provided. Noah obeyed the Lord, and the Lord shut him in.

What This Passage Means

This passage shows both God’s judgment and God’s mercy. The earth was filled with violence and corruption, so God announced judgment on all life outside the ark. But God also gave Noah clear instructions for rescue. Noah was called righteous, blameless, and one who walked with God. That does not mean he was sinless. It means he lived faithfully before the Lord.

God told Noah to build the ark exactly as commanded. Noah was to bring his family and the animals into it, along with food. The repeated line is simple and strong: Noah did all that God commanded him. When the time came, the flood began just as God had said. The waters rose over the earth, and every living thing on dry land died. Only Noah and those with him in the ark survived.

The Lord’s covenant promise stands at the center of the passage. Salvation did not come from human skill or planning. It came from God’s word and God’s provision. The Lord also shut Noah in, showing that preservation came from him.

Important Truths

  • God judges violence and corruption.
  • Noah is described as righteous, blameless, and walking with God.
  • God gives a specific way of rescue through the ark.
  • Noah obeys God’s command exactly.
  • The flood is presented as real judgment, not a mere symbol.
  • God preserves Noah’s household and the animals through his covenant promise.
  • The Lord himself shuts Noah in, showing divine protection.

Warnings, Promises, or Commands

  • Warning: the earth’s violence and corruption bring God’s judgment.
  • Warning: everything outside the ark dies in the flood.
  • Promise: God confirms his covenant with Noah.
  • Command: Noah must build the ark as instructed.
  • Command: Noah must bring his family, the animals, and food into the ark.
  • Command: Noah must do all that God commanded him.

How This Fits in God’s Plan

This passage preserves human and animal life through judgment so that God’s purposes for the world can continue. It stands early in Genesis and keeps the line of history moving toward the later covenant promises. The flood becomes a lasting Bible pattern: God judges evil, yet he provides a refuge for those under his care. In the wider canon, this pattern points forward to the saving refuge God ultimately gives in Christ, though this passage itself is not a direct messianic prophecy.

Simple Application

We should not treat sin, violence, and corruption lightly. God is holy, and he judges evil. We should also trust God’s word even before we see the outcome. Noah obeyed before the flood came. The passage calls us to reverent obedience, faith in God’s provision, and gratitude that God saves by his own mercy, not by human strength.
