Ahimaaz, "brother of anger", "irascible" in Hebrew.
(1.) The father Ahinoam, the wife of Saul (1 Sam. 14:50).
(2.) The son and successor of Zadok in the office of high priest (1 Chr. 6:8, 53). On the occasion of the revolt of Absalom he remained faithful to David, and was of service to him in conveying to him tidings of the proceedings of Absalom in Jerusalem (2 Sam. 15:24-37; 17:15-21). He was swift of foot, and was the first to carry to David tidings of the defeat of Absalom, although he refrained, from delicacy of feeling, from telling him of his death (2 Sam. 18:19-33).
(3.) A man of Solomon's court. (1 Kings 4:7,15) He was married to Basemath, daughter of Solomon. He may have been the same as nr. 2.
That Ahimaaz did not succeed his father as high priest has been inferred from the fact that in the Solomon list of heads of departments (1 Kings 4:2) Azariah the son of Zadok is mentioned as priest.
It is assumed that this Azariah is the one who appears in the genealogy as the son of Ahimaaz, and that for some reason Ahimaaz was left out of the succession.
Ahimaaz may have died early, or may have followed some other career, but the simple fact is that we do not know.
