Deuteronomy 7:14

10 But those who hate Him He repays to their faces with destruction; He will not hesitate to repay to his face the one who hates Him.

11 So keep the commandments and statutes and ordinances that I am giving you to follow this day.

12 If you listen to these ordinances and keep them carefully, then the LORD your God will keep His covenant and the loving devotion that He swore to your fathers.

13 He will love you and bless you and multiply you. He will bless the fruit of your womb and the produce of your land—your grain, new wine, and oil, the young of your herds and the lambs of your flocks—in the land that He swore to your fathers to give you.

14 You will be blessed above all peoples; among you there will be no barren man or woman or livestock.

15 And the LORD will remove from you all sickness. He will not lay upon you any of the terrible diseases you knew in Egypt, but He will inflict them on all who hate you.

16 You must destroy all the peoples the LORD your God will deliver to you. Do not look on them with pity. Do not worship their gods, for that will be a snare to you.

17 You may say in your heart, “These nations are greater than we are; how can we drive them out?”

18 But do not be afraid of them. Be sure to remember what the LORD your God did to Pharaoh and all Egypt:
