10 And Shallum the son of Jabesh conspired against him, and smote him before the people, and slew him, and reigned in his stead. 11 And the rest of the acts of Zechariah, behold, they are written in the book of the chronicles of the kings of Israel. 12 This was the word of Jehovah which he spoke to Jehu saying, Thy sons shall sit upon the throne of Israel unto the fourth [generation]. And so it came to pass.
13 Shallum the son of Jabesh began to reign in the thirty-ninth year of Uzziah king of Judah; and he reigned a full month in Samaria. 14 And Menahem the son of Gadi went up from Tirzah, and came to Samaria, and smote Shallum the son of Jabesh in Samaria, and slew him, and reigned in his stead.

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.
