The Reign of Jehoram of Judah

211 Then Jehoshaphat rested with his ancestors and was buried with them in the City of David. And Jehoram his son succeeded him as king. 2 Jehoram's brothers, the sons of Jehoshaphat, were Azariah, Jehiel, Zechariah, Azariahu, Michael and Shephatiah. All these were sons of Jehoshaphat king of Israel.[1] 3 Their father had given them many gifts of silver and gold and articles of value, as well as fortified cities in Judah, but he had given the kingdom to Jehoram because he was his firstborn son. 4 When Jehoram established himself firmly over his father's kingdom, he put all his brothers to the sword along with some of the officials 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.
