8 In the thirty-eighth year of King Azariah of Judah, Zechariah son of Jeroboam reigned over Israel in Samaria six months. 9 He did what was evil in the sight of the Lord, as his ancestors had done. He did not depart from the sins of Jeroboam son of Nebat, which he caused Israel to sin. 10 Shallum son of Jabesh conspired against him, and struck him down in public and killed him, and 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.
