Deuteronomy 7:12-13

12Listen to these rules and be careful to obey them. If you do that, the Lord your God will be faithful to the covenant that he has made with you. He promised your ancestors that he would do this.

13He will love you and he will bless you. He will give you many children so that you become a large nation. He will cause your fields to give you plenty of food: grain, wine and olive oil. He will cause your cows, sheep and goats to have many babies. That is how he will bless you in the land that he promised your ancestors to give you.
