5 Jehoram was thirty-two years old when he became king and ruled in Jerusalem for eight years. 6 He imitated Israel's kings and married into the Ahab dynasty. God considered him an evil man. 7 But despite that, because of his covenant with David, God was not yet ready to destroy the descendants of David; he had, after all, promised to keep a light burning for David and his sons.
Matthew Henry's Commentary on 2 Chronicles 21:5-7
Commentary on 2 Chronicles 21:1-11
(Read 2 Chronicles 21:1-11)
Jehoram hated his brethren, and slew them, for the same reason that Cain hated Abel, and slew him, because their piety condemned his impiety. In the mystery of Providence such men sometimes prosper for a time; but the Lord has righteous purposes in permitting such events, part of which may now be made out, and the rest will be seen hereafter.
