Genesis 9:11-15

Yes, I am confirming my covenant with you. Never again will floodwaters kill all living creatures; never again will a flood destroy the earth.” Then God said, “I am giving you a sign of my covenant with you and with all living creatures, for all generations to come. I have placed my rainbow in the clouds. It is the sign of my covenant with you and with all the earth. When I send clouds over the earth, the rainbow will appear in the clouds, and I will remember my covenant with you and with all living creatures. Never again will the floodwaters destroy all life.
