Deuteronomy 7:12-13

12“If you listen to and are careful to keep these ordinances, the Lord your God will keep his covenant loyalty with you, as he swore to your ancestors.

13He will love you, bless you, and multiply you. He will bless your offspring, and the produce of your land — your grain, new wine, and fresh oil — the young of your herds, and the newborn of your flocks, in the land he swore to your ancestors that he would give you.
