Deuteronomy 25:17-19

New Revised Standard Version Catholic Edition

¹⁷ Remember what Amalek did to you on your journey out of Egypt, ¹⁸ how he attacked you on the way, when you were faint and weary, and struck down all who lagged behind you; he did not fear God. ¹⁹ Therefore when the Lord your God has given you rest from all your enemies on every hand, in the land that the Lord your God is giving you as an inheritance to possess, you shall blot out the remembrance of Amalek from under heaven; do not forget.
