Genesis 8:20-22

20And Noah built an altar to Jehovah; and took of every clean animal, and of all clean fowl, and offered up burnt-offerings on the altar. 21And Jehovah smelled the sweet odour. And Jehovah said in his heart, I will no more henceforth curse the ground on account of Man, for the thought of Man's heart is evil from his youth; and I will no more smite every living thing, as I have done. 22Henceforth, all the days of the earth, seed [time] and harvest, and cold and heat, and summer and winter, and day and night, shall not cease.
