Abiathar

and Zadok the son of Ahitub, and Abimelech the son of Abiathar, were priests; and Shavsha was scribe;

And Shemaiah the son of Nethanel the scribe, who was of the Levites, wrote them in the presence of the king, and the princes, and Zadok the priest, and Ahimelech the son of Abiathar, and the heads of the fathers’ houses of the priests and of the Levites; one fathers’ house being taken for Eleazar, and one taken for Ithamar.

and after Ahithophel was Jehoiada the son of Benaiah, and Abiathar: and the captain of the king’s host was Joab.

How he entered into the house of God when Abiathar was high priest, and ate the showbread, which it is not lawful to eat save for the priests, and gave also to them that were with him?
