26 And the king said to Abiathar the priest, Depart thou quickly to Anathoth to thy farm, for thou art worthy of death this day; but I will not slay thee, because thou hast borne the ark of the covenant of the Lord before my father, and because thou was afflicted in all things wherein my father was afflicted.
27 And Solomon removed Abiathar from being a priest of the Lord, that the word of the Lord might be fulfilled, which he spoke concerning the house of Heli in Selom.
