1 Kings 2:27

So Solomon thrust out Abiathar from being priest unto the
Lord
He deposed him from his office of high priest, otherwise I suppose he might officiate as a common priest, at least in some of the branches of it; this was done by his own authority as a king, and not as a prophet, as Bellarmine vainly distinguishes; and not by the authority of the college of the, priests, at the instance of Solomon, as Fortunatus Schacchus says ^F4 for which there is no foundation:

that he might fulfil the word of the Lord;
which he might do intentionally, having knowledge of it, or however eventually:

which he spake concerning the house of Eli in Shiloh;
of which house Abiathar was, and which, according to that prophecy, was to be demolished, and the priesthood translated from it, which was in the line of lthamar, to another house, in the line of Eleazar; the word of the Lord, referred to, is in ( 1 Samuel 2:31-36 ) ( 3:12-14 ) .
