Deuteronomy 7:12-15

If you pay attention to these laws and obey them carefully, the LORD your God will keep his agreement and show his love to you, as he promised your ancestors. He will love and bless you. He will make the number of your people grow; he will bless you with children. He will bless your fields with good crops and will give you grain, new wine, and oil. He will bless your herds with calves and your flocks with lambs in the land he promised your ancestors he would give you. You will be blessed more than any other people. Every husband and wife will have children, and all your cattle will have calves. The LORD will take away all disease from you; you will not have the terrible diseases that were in Egypt, but he will give them to all the people who hate you.
