What symbol marked God’s covenant after Noah’s Ark and the Flood?

A rainbow marked God’s covenant after Noah’s Ark and the Flood.

Genesis 9 describes God’s covenant with Noah, his descendants, and every living creature after Noah leaves the ark. The rainbow is presented as the sign of that covenant and as a reminder that the waters will not again become a flood destroying all life.

The rainbow is therefore different from the dove and the olive leaf. Noah’s birds help reveal that the waters are receding, while the rainbow appears afterward as the covenant sign. These related images are often blended together in retellings, but Genesis assigns them different roles.

The covenant extends beyond Noah’s family to the animals and the earth. It is one of the story’s major conclusions, shifting the focus from survival inside the ark to a promise concerning the future of the world. The account does not describe the rainbow as a symbol Noah invented; it describes it as a sign established by God.
