[9] But the king was greatly offended at these words, and sent away his mother, and said that Adonijah aimed at great things; and that he wondered that she did not desire him to yield up the kingdom to him, as to his elder brother, since she desired that he might marry Abishag; and that he had potent friends, Joab the captain of the host, and Abiathar the priest. So he called for Benaiah, the captain of the guards, and ordered him to slay his brother Adonijah. He also called for Abiathar the priest, and said to him, "I will not put thee to death because of those other hardships which thou hast endured with my father, and because of the ark which thou hast borne along with him; but I inflict this following punishment upon thee, because thou wast among Adonijah's followers, and wast of his party. Do not thou continue here, nor come any more into my sight, but go to thine own town, and live on thy own fields, and there abide all thy life; for thou hast offended so greatly, that it is not just that thou shouldst retain thy dignity any longer." For the forementioned cause, therefore, it was that the house of Ithamar was deprived of the sacerdotal dignity, as God had foretold to Eli, the grandfather of Abiathar. So it was transferred to the family of Phineas, to Zadok. Now those that were of the family of Phineas, but lived privately during the time that the high priesthood was transferred to the house of Ithamar, (of which family Eli was the first that received it,)were these that follow: Bukki, the son of Abishua the high priest; his son was Joatham; Joatham's son was Meraioth; Meraioth's son was Arophseus; Aropheus's son was Ahitub; and Ahitub's son was Zadok, who was first made high priest in the reign of David.
