The Bible’s story of Noah building the Ark appears in the Book of Genesis.
The account begins in Genesis chapters 6–9. It describes a world filled with violence, God’s decision to send a flood, Noah’s instructions to build an ark, and the survival of Noah, his family, and animals. After the flood, the story continues with the covenant symbolized by a rainbow.
Genesis is the first book of both the Hebrew Bible and the Christian Old Testament. Its early chapters include other foundational narratives, including creation, Adam and Eve, Cain and Abel, and the Tower of Babel.
A common mix-up is identifying Exodus as the source of the Ark story. Exodus contains the account of Moses and the Israelites leaving Egypt, as well as the Ark of the Covenant, which is a different object from Noah’s Ark.
