Deuteronomy 7:13-16

7:13 He will love and bless you, and make you numerous. He will bless you with many children, with the produce of your soil, your grain, your new wine, your oil, the offspring of your oxen, and the young of your flocks in the land which he promised your ancestors to give you. 7:14 You will be blessed beyond all peoples; there will be no barrenness among you or your livestock. 7:15 The Lord will protect you from all sickness, and you will not experience any of the terrible diseases that you knew in Egypt; instead he will inflict them on all those who hate you.
