Deuteronomy 25:17-19

NHEB(i) 17 Remember what Amalek did to you by the way as you came forth out of Egypt; 18 how he met you by the way, and struck the hindmost of you, all who lagged behind you, when you were faint and weary; and he did not fear God. 19 Therefore it shall be, when the LORD your God has given you rest from all your enemies all around, in the land which the LORD your God gives you for an inheritance to possess it, that you shall blot out the memory of Amalek from under the sky; you shall not forget.
