Deuteronomy 25:18-19

Young's Literal Translation

¹⁸ that he hath met thee in the way, and smiteth in all those feeble behind thee (and thou wearied and fatigued), and is not fearing God.

¹⁹ And it hath been, in Jehovah thy God's giving rest to thee, from all thine enemies round about, in the land which Jehovah thy God is giving to thee -- an inheritance to possess it -- thou dost blot out the rememberance of Amalek from under the heavens -- thou dost not forget.
