And unto Abiathar the priest said the king: ‘Get thee to Anathoth, unto thine own fields; for thou art deserving of death; but I will not at this time put thee to death, because thou didst bear the ark of the Lord GOD before David my father, and because thou wast afflicted in all wherein my father was afflicted.’
Ibn Ezra
