Then Noah built an altar to the LORD. And taking from every kind of clean animal and clean bird, he offered burnt offerings on the altar. When the LORD smelled the pleasing aroma, He said in His heart, ”Never again will I curse the ground because of man, even though every inclination of his heart is evil from his youth. And never again will I destroy all living creatures as I have done. As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, day and night shall never cease.” … And God said, “This is the sign of the covenant I am making between Me and you and every living creature with you, a covenant for all generations to come: I have set My rainbow in the clouds, and it will be a sign of the covenant between Me and the earth.”
Genesis 8:20-22; 9:12-13 (BSB)
