In the biblical Noah's Ark story, Noah built the ark at God's command. Genesis presents Noah as a righteous man living in a world described as corrupt and violent. God tells him to construct a huge vessel, preserve his family, and bring aboard animals before a flood covers the earth.
The account names Noah as the builder and central human figure. His sons—Shem, Ham, and Japheth—also enter the ark with their wives, so the narrative portrays the project as a family undertaking even though Noah receives the instructions.
Noah is also important after the flood. He leaves the ark, builds an altar, and receives a covenant symbolized by the rainbow. The story is often confused with later flood traditions, but in the Hebrew Bible the ark's builder is specifically Noah.
The Qur'an also tells a flood story involving Nuh, the Arabic name for Noah, although details differ between the traditions.
