1 Samuel 22:18-23

18And the king said to Doeg, Turn thou, and fall upon the priests. And Doeg the Edomite turned, and he fell upon the priests, and slew on that day fourscore and five persons that did wear a linen ephod. 19And Nob, the city of the priests, smote he with the edge of the sword, both men and women, children and sucklings, and oxen, and asses, and sheep, with the edge of the sword.

20And one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped, and fled after David. 21And Abiathar shewed David that Saul had slain the Lord’s priests. 22And David said unto Abiathar, I knew it that day, when Doeg the Edomite was there, that he would surely tell Saul: I have occasioned the death of all the persons of thy father’s house. 23Abide thou with me, fear not: for he that seeketh my life seeketh thy life: but with me thou shalt be in safeguard.
