Boyd’s Bible Dictionary:
(lord of heights). Chief receiver of tribute under David, Solomon, and Rehoboam (1 Kings 4:6). Written Adoram (2 Sam. 20:24; 1 Kings 12:18); and Hadoram (2 Chron. 10:18).
Concise Bible Dictionary:
Chief over the tribute in the days of Solomon (1 Kings 4:6; 5:14). In David’s time ADORAM was over the tribute (2 Sam. 20:24), and in the days of Rehoboam also a person of this name was over the tribute (1 Kings 12:18), which Gesenius and others take to be a contracted form of Adoniram, and to refer to the same person. Apparently the Adoram mentioned in 1 Kings 12:18 is called HADORAM in 2 Chronicles 10:18. All Israel stoned him to death at the revolt of the ten tribes. If Adoniram held office from David to Rehoboam it would embrace a long period; still it may be the same throughout, or father and son.
