New Defender's Study Bible Notes
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.
