New Defender's Study Bible Notes
5:1 king of Syria. Whether this king was Ben-Hadad I, Ben-Hadad II, or Hazael, is a matter of uncertainty, depending on whether II Kings 5 occurs here in chronological order or not. See below, on footnote for II Kings 5:5.
5:5 king of Israel. If these chapters are in chronological order, this king would be Jehoram. Some believe that the infliction of leprosy on Gehazi must have been considerably later, since Israel’s law required the ostracism of lepers, and Gehazi was still actively serving Elisha some years later (II Kings 8:4). In that case, Jehoahaz was most likely the king.
5:15 but in Israel. This unique testimony by the commanding general of the great army of Syria is eloquent witness to the unique power of the one true God of creation. None of the Syrian “gods” could cure Naaman’s incurable leprosy, but God did, once Naaman had humbled himself, and believed.
5:17 unto other gods. Naaman was a worthy man, so that his military victories had been given by the Lord (II Kings 5:1), possibly already at least partially trusting the God of Israel as a result of the testimony of the captive maid (II Kings 5:4). After his miraculous healing he became a true believer, though still forced to give nominal allegiance to the gods of Syria (II Kings 5:18).
5:17 two mules’ burden of earth. Naaman apparently believed that, if he was going to worship the God of Israel henceforth, he would need to have some of the ground of Israel on which to do so.
5:27 a leper as white as snow. By this act of cupidity, Gehazi forfeited his right to be Elisha’s successor. Many a talented servant of God since that day has forfeited his ministry by similar greedy acts.
