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. Esther 3:1
Agag and all Amalekites were killed in a God-ordained genocide.
Thus saith the LORD of hosts ... Now go and smite Amalek, and utterly destroy all that they have,
and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.
1 Samuel 15:2-3
And Saul smote the Amalekites ... And he took Agag the king of the Amalekites alive, and utterly destroyed all the people
with the edge of the sword. 1 Samuel 15:7-8
Then said Samuel, Bring ye hither to me Agag the king of the Amalekites. And Agag came unto him delicately. And Agag said,
Surely the bitterness of death is past. And Samuel said, As the sword hath made women childless, so shall thy mother be childless
among women. And Samuel hewed Agag in pieces before the LORD in Gilgal. 1 Samuel 15:32-33
