1 Kings 2:27

Verse 1 Kings 2:27. So Solomon thrust out Abiathar] This was for having taken part before with Adonijah, but by it a remarkable prophecy was fulfilled; see 1 Samuel 2:13-9, and the notes there. God had told Eli that the priesthood should depart from his house; Abiathar was the last of the descendants of Ithamar, of which family was Eli the high priest. Zadok, who was made priest in the stead of Abiathar, was of the family of Eliezer; and by this change the priesthood reverted to its ancient channel. Abiathar deserved this degradation; he supported Adonijah in his unnatural assumption of the royal dignity, even during the life of his father. This was the head and front of his offending.
