Ahithophel

brother of insipidity or impiety, a man greatly renowned for his
sagacity among the Jews. At the time of Absalom's revolt he
deserted David (Ps. 41:9; 55:12-14) and espoused the cause of
Absalom (2 Sam. 15:12). David sent his old friend Hushai back to
Absalom, in order that he might counteract the counsel of
Ahithophel (2 Sam. 15:31-37). This end was so far gained that
Ahithophel saw he had no longer any influence, and accordingly
he at once left the camp of Absalom and returned to Giloh, his
native place, where, after arranging his wordly affairs, he
hanged himself, and was buried in the sepulchre of his fathers
(2 Sam. 17:1-23). He was the type of Judas (Ps. 41:9).
