10 Shallum son of Jabesh conspired against him, assassinated him in public view, and took over as king. 11 The rest of the life and times of Zechariah is written plainly in The Chronicles of the Kings of Israel. 12 That completed the word of God that was given to Jehu, namely, "For four generations your sons will sit on the throne of Israel." Zechariah was the fourth.
13 Shallum son of Jabesh became king in the thirty-ninth year of Azariah king of Judah. He was king in Samaria for only a month. 14 Menahem son of Gadi came up from Tirzah to Samaria. He attacked Shallum son of Jabesh and killed him. He then became king.

Commentary on 2 Kings 15:8-31
(Read 2 Kings 15:8-31)
This history shows Israel in confusion. Though Judah was not without troubles, yet that kingdom was happy, compared with the state of Israel. The imperfections of true believers are very different from the allowed wickedness of ungodly men. Such is human nature, such are our hearts, if left to themselves, deceitful above all things, and desperately wicked. We have reason to be thankful for restraints, for being kept out of temptation, and should beg of God to renew a right spirit within us.
