Deuteronomy 25:17-19 - Revenge On The Amalekites
17 Remember what Amalek did to you along the way when you came out from Egypt. 18 He met you along the way and attacked among you all the stragglers at your rear when you were faint and weary. He did not respect God. 19 When Jehovah your God has given you rest from all your surrounding enemies, in the land Jehovah your God gives you as an inheritance to possess. You will blot out the memory of Amalek from under heaven. Do not forget.
