19 All the animals and birds went out of the boat in groups of their own kind.
20 Noah built an altar to the Lord; he took one of each kind of ritually clean animal and bird, and burned them whole as a sacrifice on the altar.
21 The odor of the sacrifice pleased the Lord, and he said to himself, “Never again will I put the earth under a curse because of what people do; I know that from the time they are young their thoughts are evil. Never again will I destroy all living beings, as I have done this time.
22 As long as the world exists, there will be a time for planting and a time for harvest. There will always be cold and heat, summer and winter, day and night.”
