20 Then Noah built an altar to the Lord, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar. 21 And when the Lord smelled the pleasing odor, the Lord said in his heart, “I will never again curse the ground because of man, for the imagination of man’s heart is evil from his youth; neither will I ever again destroy every living creature as I have done. 22 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease.”
