Zadok . . . and Ahimelech . . . were the priests—On the massacre of the priests at Nob, [1Sa 22:19], Saul conferred the priesthood on Zadok, of the family of Eleazar (1Ch 6:50), while David acknowledged Ahimelech, of Ithamar's family, who fled to him. The two high priests exercised their office under the respective princes to whom they were attached. But, on David's obtaining the kingdom over all Israel, they both retained their dignity; Ahimelech officiating at Jerusalem, and Zadok at Gibeon (1Ch 16:39).
