TSK · Numbers 24:20

Then came Amalek, and fought with Israel in Rephidim.

and he said, Jehovah hath sworn: Jehovah will have war with Amalek from generation to generation.

And he did valiantly, and smote the Amalekites, and delivered Israel out of the hands of them that despoiled them.

And David and his men went up, and made a raid upon the Geshurites, and the Girzites, and the Amalekites; for those [nations] were the inhabitants of the land, who were of old, as thou goest to Shur, even unto the land of Egypt.

And David smote them from the twilight even unto the evening of the next day: and there escaped not a man of them, save four hundred young men, who rode upon camels and fled.

After these things did king Ahasuerus promote Haman the son of Hammedatha the Agagite, and advanced him, and set his seat above all the princes that were with him.

And the king commanded it so to be done: and a decree was given out in Shushan; and they hanged Haman's ten sons.
