30:7 Abiathar. Abiathar was the son of Ahimelech, who had been chief priest at the time Saul had Doeg the Edomite slaughter all the priests serving under Ahimelech (I Samuel 22:18). Abiathar alone had escaped (I Samuel 22:20), and so was serving as chief priest under David, possessing the ephod with the Urim and Thummim.
