1 Kings 2:27 - Matthew Poole's English Annotations on the Holy Bible

From being priest unto the Lord; either from his office, or at least, from the execution of his office. For some think that he was thrust from his office before David's death, when Zadok was formerly made priest, i.e. high priest, in his stead, 1 Chronicles 29:22. But that seems to be a mistake; for although that passage immediately follows the history of what was done in the time of David's life and health, when he was in a capacity of going into the public congregation; yet it manifestly belongs to another time, and was done after it; for he there speaks of Solomon's being made king the second time, and he was made king but twice; once undoubtedly before this, 1 Chronicles 23:1; and again 1 Kings 1:39; when David was bedrid, and Adonijah's usurpation made a second unction necessary. And therefore what is said 1 Chronicles 29:22, of Zadok's being made priest, was done after Abiathar's deposition, and upon that occasion. That he might fulfil the word of the Lord; for what hinders but Solomon might intend this not only as a punishment for his treason, but also as a means to accomplish God's word? Concerning the house of Eli, i.e. concerning the translation of the priesthood from the house of Eli, and of Ithamar, unto that of Eleazar; which being threatened eighty years ago, is now executed. So Divine vengeance, though sometimes it be slow, is always sure.
