God promised to never again destroy all the people with a flood

20 Then Noah built a ◄stone altar/place for offering sacrifices► to Yahweh. Then he took some of the animals that Yahweh had said were acceptable as sacrifices and killed them. Then he burned them whole on the altar. 21 When Yahweh smelled the pleasant odor, he was pleased with the sacrifice. Then he said to himself, “I will never again devastate everything on the earth because of the sinful things people do. Even though everything that people think is evil from the time they are young, I will not destroy all the living creatures again, as I did this time. 22 As long as the earth exists, each year there will be seasons for planting seeds and seasons for harvesting crops. Each year there will be times when it is cold and times when it is hot, summer and winter (OR, rainy season and dry season). Each day there will be daytime and nighttime.”
