Boyd’s Bible Dictionary:
Subject of Agag (Esther 3:1-10).
Concise Bible Dictionary:
Haman was the son of Hammedatha the Agagite (Esther 3:1-10; Esther 8:3, 5; Esther 9:24). Furst says the Gentile name “of Haman is therefore explained by Josephus τὸ γένος Ἀμυλεκίτες, and so too by Jewish tradition.” That is, that Haman was an Amalekite. This explains why Mordecai refused to bow down before Haman. He was of that race with which Jehovah had sworn to have war forever, and which Saul was directed to utterly exterminate (Ex. 17:16; Deut. 25:19; 1 Sam. 15:3).
