1 Samuel 22:20-22

20 But Abiathar son of Ahimelech escaped. He ran away and joined David.

21 Abiathar told David that Saul had killed the LORD’S priests.

22 Then David told Abiathar, “I saw Doeg the Edomite at Nob that day. I knew he would tell Saul! I am responsible for the death of your father’s family.
