Deuteronomy 25:17-19 New American Bible, Revised Edition (NABRE)

17. Bear in mind what Amalek did to you on the journey after you left Egypt,

18. how he surprised you along the way, weak and weary as you were, and struck down at the rear all those who lagged behind; he did not fear God.

19. Therefore, when the Lord, your God, gives you rest from all your enemies round about in the land which the Lord, your God, is giving you to possess as a heritage, you shall blot out the memory of Amalek from under the heavens. Do not forget!
