1 Samuel 22:18-22

Then the king said to Doeg, “You, turn around and attack the priests!” And Doeg the Edomite turned around and attacked the priests, and he killed on that day eighty-five men who wore the linen ephod.

He also struck Nob the city of the priests with the edge of the sword, both men and women, children and infants; he also struck oxen, donkeys, and sheep with the edge of the sword.

But one son of Ahimelech the son of Ahitub, named Abiathar, escaped and fled to David.

Abiathar informed David that Saul had killed the priests of the Lord.

Then David said to Abiathar, “I knew on that day, when Doeg the Edomite was there, that he would certainly tell Saul. I myself have turned against every person in your father’s household.
