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. 15 Now the rest of the deeds of Shallum, including the conspiracy that he made, are written in the Book of the Annals of the Kings of Israel. 16 At that time Menahem sacked Tiphsah, all who were in it and its territory from Tirzah on; because they did not open it to him, he sacked it. He ripped open all the pregnant women in it.
17 In the thirty-ninth year of King Azariah of Judah, Menahem son of Gadi began to reign over Israel; he reigned ten years in Samaria. 18 He did what was evil in the sight of the Lord; he did not depart all his days from any of the sins of Jeroboam son of Nebat, which he caused Israel to sin. 19 King Pul of Assyria came against the land; Menahem gave Pul a thousand talents of silver, so that he might help him confirm his hold on the royal power. 20 Menahem exacted the money from Israel, that is, from all the wealthy, fifty shekels of silver from each one, to give to the king of Assyria. So the king of Assyria turned back, and did not stay there in the land. 21 Now the rest of the deeds of Menahem, and all that he did, are they not written in the Book of the Annals of the Kings of Israel? 22 Menahem slept with his ancestors, and his son Pekahiah succeeded him.

(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.
