1 Kings 22:50

And Jehoshaphat slept with his fathers, and was buried with his fathers in the city of David his father: and Jehoram his son reigned in his stead.

Ver. 50. And Jehoram his son.] His most wicked son, for so he proved, 2 Chronicles 21:6 , &c. being the worse doubtless for his wife Athaliah, the daughter of Ahab; between whom and good Jehoshaphat there was so great a league, that they gave the same names to each other's children: Jehoshaphat called his son Jehoram - marrying him to Ahab's daughter; and Jehoram called his son Ahaziah; and Ahab called his sons Ahaziah and Jehoram. Jehoshaphat also, by Ahab's example, made his son Jehoram Prorex: whence Jehoram the son of Ahab is said 2Ki 1:17 to have begun to reign in the second year of Jehoram son of Jehoshaphat king of Judah.
