19 So when the Lord your God gives you relief from all the enemies who surround you in the land he is giving you as an inheritance, you must wipe out the memory of the Amalekites from under heaven—do not forget!

Darby

19 And it shall be, when Jehovah thy God shall have given thee rest from all thine enemies round about, in the land that Jehovah thy God giveth thee for an inheritance to possess it, that thou shalt blot out the remembrance of Amalek from under the heavens; thou shalt not forget it.

KJV

19 Therefore it shall be, when the LORD thy God hath given thee rest from all thine enemies round about, in the land which the LORD thy God giveth thee [for] an inheritance to possess it, [that] thou shalt blot out the remembrance of Amalek from under heaven; thou shalt not forget [it].
