4 And Jehoram established himself over the kingdom of his father, and strengthened himself; and he slew all his brethren with the sword, and [certain] also of the princes of Israel.

Matthew Henry's Commentary on 2 Chronicles 21:4

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.
