1 Samuel 22:18-22

Then the king said to Doeg, “You turn and strike the priests.” And Doeg the Edomite turned and struck down the priests, and he killed on that day eighty-five persons who wore the linen ephod. And Nob, the city of the priests, he put to the sword; both man and woman, child and infant, ox, donkey and sheep, he put to the sword. But one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped and fled after David. And Abiathar told David that Saul had killed the priests of the LORD. And David said to Abiathar, “I knew on that day, when Doeg the Edomite was there, that he would surely tell Saul. I have occasioned the death of all the persons of your father’s house.
