1 Samuel 22
20 Ref And one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped, and fled after David.
21 And Abiathar showed David that Saul had slain the LORD's priests.
22 Ref 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.
