8 In the thirty-eighth year of Azaliah, king of Judah, Zechariah, son of Jeroboam, was king over Israel for six months. 9 And he did evil in the eyes of the Lord, as his father had done, not turning away from the sin which Jeroboam, the son of Nebat, did and made Israel do. 10 And Shallum, the son of Jabesh, made a secret design against him, and, attacking him in Ibleam, put him to death and became king in his place. 11 Now the rest of the acts of Zechariah are recorded in the book of the history of the kings of Israel. 12 This was what the Lord had said to Jehu, Your sons to the fourth generation will be kings of Israel. And so it came about.
13 Shallum, the son of Jabesh, became king in the thirty-ninth year of Uzziah, king of Judah; and he was ruling in Samaria for the space of one month. 14 Then Menahem, the son of Gadi, went up from Tirzah and came to Samaria, and attacking Shallum, son of Jabesh, in Samaria, put him to death and made himself king in his place. 15 Now the rest of the acts of Shallum, and the secret design which he made, are recorded in the book of the history of the kings of Israel. 16 Then Menahem sent destruction on Tappuah and all the people in it, and its limits, from Tirzah, because they would not let him come in; and he had all the women who were with child cut open.

(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.
