Parashat Noach (Genesis 6:9-11:32)
When Noah and his family came out of the ark, God told them to be fruitful and multiply, repopulating the earth. He also entrusted them with certain moral obligations regarding the treatment of both man and animal. Last, He made a covenant with humanity to never again destroy the earth by water and created the rainbow as a testimony to this covenant:
And God said, “This is the sign of the covenant that I make between me and you and every living creature that is with you, for all future generations: I have set my bow in the cloud, and it shall be a sign of the covenant between me and the earth. When I bring clouds over the earth and the bow is seen in the clouds, I will remember my covenant that is between me and you and every living creature of all flesh. And the waters shall never again become a flood to destroy all flesh. (Genesis 9:12–15)
