Context Reading
17Remember what Amalek did to you by the way as you came out of Egypt, 18how he met you by the way, and struck the rearmost of you, all who were feeble behind you, when you were faint and weary; and he didn’t fear God. 19Therefore it shall be, when Yahweh your God has given you rest from all your enemies all around, in the land which Yahweh 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.
