The story in 6 steps
A world gone wrong, and one man who walked with God
Genesis 6:5–13
Genesis describes the earth as corrupt and full of violence, and God grieves that he made humankind. Noah stands out. The text describes him as righteous, without blame in his generation, and says he walked with God.
God tells Noah to build an ark
Genesis 6:14–22
God gives Noah exact plans: a boat of gopher wood, coated with pitch, about 300 by 50 by 30 cubits, with three decks and a door in the side. He is to bring his family and pairs of every kind of living creature, plus food. Noah does everything God commands.
The family and the animals go in
Genesis 7:1–16
God tells Noah to take seven pairs of every clean animal and one pair of every other kind. Noah is 600 years old when he, his wife, his three sons Shem, Ham and Japheth, and their wives enter the ark. The text adds a quiet detail: the LORD himself shuts them in.
The flood covers the earth
Genesis 7:17–24
Rain falls for forty days and forty nights, and the waters rise above the highest mountains. Every living thing on dry land outside the ark dies. Only Noah, his household and the animals with them survive, and the waters stay high for 150 days.
The raven, the dove and the olive leaf
Genesis 8:1–14
God remembers Noah, a wind passes over the earth and the waters begin to fall. The ark settles on the mountains of Ararat. Noah sends out a raven, then a dove three times; the second time the dove returns with a fresh olive leaf, and the third time it does not come back.
The altar and the rainbow promise
Genesis 8:15–9:17
God tells Noah to leave the ark, and Noah builds an altar and offers sacrifices. God blesses Noah's family and makes a covenant with them, with every living creature and with the earth: never again will a flood destroy all life. The rainbow in the clouds is the sign of that promise.

Who is in the story
- Noah — The righteous man who builds the ark and obeys God's instructions
- Noah's wife — Enters the ark with the family; the text does not give her name
- Shem, Ham and Japheth — Noah's three sons, who survive the flood with their wives
- God (the LORD) — Judges the violence on earth, saves Noah's family and makes the covenant
What the story teaches
The story holds judgment and mercy side by side. Genesis presents the flood as God's response to violence and corruption, yet the same God makes a way through it for Noah's family and for every kind of animal. Many readers see the ark as a picture of rescue rather than only of destruction.
Noah's obedience is a central thread. The text twice notes that he did everything God commanded, even though the task was huge and the reason for it was not yet visible. Jewish and Christian teachers alike have pointed to Noah as an example of faithfulness in a hostile setting; the letter to the Hebrews lists him among people of faith (Hebrews 11:7).
The ending is a covenant, a word that first appears in the Bible in this story (Genesis 6:18). God binds himself by a promise to all living things, not only to Noah, and chooses the rainbow as its sign. Christian tradition has often read the ark as a picture of salvation (see 1 Peter 3:20–21), while Jewish tradition draws from Genesis 9 the idea of basic moral laws for all humanity, often called the Noahide laws.
Readers also differ on how to read the flood itself. Some take it as a worldwide historical event, others as a regional flood described in the language of its time, and others as a theological narrative. The text's own focus stays on God's response to evil, his care for life and his faithfulness to his word.
Faithfulness when others mock or ignore
Noah keeps doing what he was told, step by step, in a world that was going the other way.
God remembers
The turning point of the story is the line that God remembered Noah; the flood ends because God acts.
Promises with signs
The rainbow shows a God who commits himself publicly and lets people see his promise.
How big was the ark?
Genesis 6:15 gives the size as 300 cubits long, 50 wide and 30 high. A cubit was roughly the length of a forearm, so estimates usually land around 135–155 meters (about 450–510 feet) long. Exact figures depend on which cubit is assumed.
The text says the ark had three decks, a roof with an opening, and one door in the side. It does not describe a mast, sails or steering, which fits its purpose: to stay afloat, not to travel.

Questions for discussion
- Why do you think Genesis describes God as grieving, not only angry, before the flood?
- Noah obeyed before he could see why. When is it hard to do the right thing without knowing how it will turn out?
- What does the detail that God shut the door of the ark suggest to you?
- The covenant in Genesis 9 includes animals and the earth itself. What does that say about how God values creation?
- What could a rainbow remind you of the next time you see one?
