Deuteronomy 25:17-19
Revenge on the Amalekites

17 Remember what Amalek did unto thee by the way, when ye were come forth out of Egypt;

17:

18 How he met thee by the way, and smote the hindmost of thee, [even] all [that were] feeble behind thee, when thou [wast] faint and weary; and he feared not God.

18:

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].

19:
