Doeg the Edomite was one of King Saul's chief henchmen. David, on the run from Saul, went to Ahimelech, the priest of Nob, who gave David the holy bread for food. Doeg was in the area that day and saw David and later reported this to Saul. Saul, in a rage, felt that Ahimelech conspired against him in helping David.
Saul ordered his men to kill all the priests, "But the king's servants refused to lift a hand to strike the Priests of the Lord." Saul then commanded Doeg to kill the priests. "So Doeg the Edomite went from one to the next and killed the priests himself, slaying on that day eighty-five who wore the linen ephod.".[1]
