1 Samuel 22:20-22

King James Version

²⁰ And one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped, and fled after David.

²¹ And Abiathar shewed David that Saul had slain the Lord's priests.

²² And 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.
