211 And Jehoshaphat lieth with his fathers, and is buried with his fathers in the city of David, and Jehoram his son reigneth in his stead. 2 And he hath brethren, sons of Jehoshaphat, Azariah, and Jehiel, and Zechariah, and Azariah, and Michael, and Shephatiah; all these 'are' sons of Jehoshaphat king of Israel, 3 and their father giveth to them many gifts of silver and of gold, and of precious things, with fenced cities in Judah, and the kingdom he hath given to Jehoram, for He 'is' the first-born. 4 And Jehoram riseth up over the kingdom of his father, and strengtheneth himself, and slayeth all his brethren with the sword, and also—of the heads of Israel.

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.
