Shmuel Alef 22:20-22

Orthodox Jewish Bible

²⁰ And ben echad of Achimelech Ben Achituv, shmo Evyatar (his name Evyatar [Abiathar]), escaped, and fled after Dovid.

²¹ And Evyatar (Abiathar) told Dovid that Sha’ul had slain the Kohanim of Hashem.

²² And Dovid said unto Evyatar (Abiathar), I knew it that day, when Do’eg the Edomi was there, that he would surely tell Sha’ul. I am mortally responsible for nefesh Bais Avicha.
