What promise did God make after Noah’s Ark landed, according to Genesis?

After the flood, Genesis says God promised never again to destroy the earth by flood. This covenant is made with Noah, his descendants, and every living creature after Noah leaves the Ark.

The sign of the covenant is the rainbow. In Genesis 9, God says the rainbow in the cloud will remind him of the covenant between God and the earth. The promise is specifically about a flood destroying all life; it is not a promise that rain will never occur again.

The passage also introduces other post-flood instructions and blessings, including permission to eat animals and a prohibition against consuming blood. Noah and his descendants are told to be fruitful and multiply.

This covenant is distinct from later biblical covenants associated with figures such as Abraham or Moses. The rainbow is therefore tied in Genesis to the Noahic covenant and its promise concerning a universal flood, not to the construction of the Ark itself.
