1 Samuel 22:20-24

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

And Abiathar shewed David that Saul had slain the LORD’s priests.

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.

Abide thou with me, fear not: for he that seeketh my life seeketh thy life: but with me thou shalt be in safeguard.
