Deuteronomy 25:17-19

CAB(i) 17 Remember what things Amalek did to you by the way, when you went forth out of the land of Egypt, 18 how he withstood you in the way, and harassed your rear, even those that were weary behind you, and you hungered and were weary; and he did not fear God. 19 And it shall come to pass whenever the Lord your God shall have given you rest from all your enemies round about you, in the land which the Lord your God gives you to inherit, you shall blot out the name of Amalek from under heaven, and shall not forget to do it.
