1 Samuel 22:21-23

When he told David that Saul had killed the priests of the LORD, David exclaimed, “I knew it! When I saw Doeg the Edomite there that day, I knew he was sure to tell Saul. Now I have caused the death of all your father’s family. Stay here with me, and don’t be afraid. I will protect you with my own life, for the same person wants to kill us both.”
