10 Shallum son of Jabesh conspired against him, and struck him down in public and killed him, and reigned in place of him. 11 Now the rest of the deeds of Zechariah are written in the Book of the Annals of the Kings of Israel. 12 This was the promise of the Lord that he gave to Jehu, "Your sons shall sit on the throne of Israel to the fourth generation." And so it happened.
13 Shallum son of Jabesh began to reign in the thirty-ninth year of King Uzziah of Judah; he reigned one month in Samaria. 14 Then Menahem son of Gadi came up from Tirzah and came to Samaria; he struck down Shallum son of Jabesh in Samaria and killed him; he reigned in place of him.

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.
