Genesis 8:21-22

And 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. Henceforth, 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.
