Then Noah built an altar to the Lord. He took some of every kind of clean animal and every kind of clean bird and offered burnt offerings on the altar.
When the Lord smelled the pleasing aroma, He said to Himself, "I will never again curse the ground because of man, even though man's inclination is evil from his youth. And I will never again strike down every living thing as I have done.
References for Genesis 8:21
