Deuteronomy 25:18-19

Amplified Bible, Classic Edition

¹⁸ How he did not fear God, but when you were faint and weary he attacked you along the way and cut off all the stragglers at your rear.^(A)

¹⁹ Therefore when the Lord your God has given you rest from all your enemies round about in the land which the Lord your God gives you to possess as an inheritance, you shall blot out the remembrance of Amalek from under the heavens; you must not forget.
