2 Samuel 8:17

The son of Ahitub; not of that Ahitub, 1Sa 22; for that was of Ithamar's race, but this of Eleazar. Ahimelech the son of Abiathar; so Abiathar called his son by the name of his father, 1 Samuel 22:20. The priests, i. e. the chief priest next under Abiathar, who fled to David, 1 Samuel 22:20, and now was high priest, as may be gathered from 2 Samuel 15:35 1 Kings 2:27,35: under him these two were the next chief priests, or the second priests, each one being chief of the house of his father, Zadok of Eleazar, and Ahimelech of Ithamar. See Numbers 3:32 1 Chronicles 24:3,4. Or these two are here mentioned, because they constantly attended upon the king, that he might consult with them in the matters of the Lord, as need required.
