(13) A full month.--Literally, as margin. Thenius says Shallum cannot have reigned a full month, as Zechariah 11:8 obviously refers to the three kings Zachrriah, Shallum, and Menahem.

Verses 13-15. - SHORT AND UNIMPORTANT REIGN OF SHALLUM. Three verses suffice for the reign of Shallum, the son of Jabesh, who held the throne for only thirty days. Hearing of his conspiracy, Menahem, the son of Gadi - "the general," as Josephus calls him ('Ant. Jud.,' 10:11. § 1) - marched from Tirzah to Samaria, got Shallum into his power, and put him to death (ver. 14). The writer concludes with the usual formula (ver. 15). Verse 13. - Shallum the son of Jabesh began to reign in the nine and thirtieth year of Uzziah King of Judah. This date follows from that of ver. 8, and must stand or fall with it. The true accession-year of Shallum was probably the twenty-seventh of Uzziah. And he reigned a fall month in Samaria; literally, a month of days - "thirty days" according to Josephus.

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.Shallum the son of Jabesh began to reign in the nine and thirtieth year of Uzziah king of Judah,.... The same with Azariah: he is sometimes called by one name, and sometimes by the other, see 2 Kings 14:21,

and he reigned a full month in Samaria: and no longer; so soon were the conspiracy against his sovereign, and the murder of him, punished.
