8 In the thirty-eighth year of Azariah king of Judah, Zechariah the son of Jeroboam reigned over Israel in Samaria six months. 9 And he did what was evil in the sight of the Lord, as his fathers had done. He did not depart from the sins of Jeroboam the son of Nebat, which he made Israel to sin. 10 Shallum the son of Jabesh conspired against him and struck him down at Ibleam and put him to death and reigned in his place. 11 Now the rest of the deeds of Zechariah, behold, they are written in the Book of the Chronicles 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 came to pass.)

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.
