7 Yet the Lord would not destroy the house of David, because of the covenant which he had made with David, and since he had promised to give a lamp to him and to his sons for ever.

Matthew Henry's Commentary on 2 Chronicles 21:7

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.
