(1) Father of Achinoam, wife of Saul (1 Samuel 14:50).
(2) Son of Sadoc, the priest. He was a swift-footed messenger in the service of David during the rebellion of Absalom. He brought from Jerusalem news of the enemy's movements, and, after the battle in which Absalom was slain, he was the first to reach the King with the news of victory. He was "a good man", according to David (2 Samuel 15:35-36; 17:17 ff.; 18:19 ff.). This Achimaas is perhaps the same as one of Solomon's prefects, the governor of Nephtali, and son-in-law of the King (1 Kings 4:15).
