“King Shallum son of Jabesh began to reign in the thirty-ninth year of King Azariah of Judah. He reigned one month in Samaria. Then Menahem son of Gadi came up from Tirzah. He came to Samaria. He struck down King Shallum son of Jabesh in Samaria and killed him. He reigned in his place. Now the rest of the deeds of King Shallum, including the conspiracy that he made, are written in the Book of the Annals of the Kings of Israel. At that time King Menahem sacked Tappuah, all who were in it and its territory from Tirzah on. As they did not open it to him, therefore he sacked it. He ripped up all the pregnant women in it.”
While this reign was longer than the 7 days of King Zimri, 1 month is quite short. King Shallum lasted only a month, when Menahem, who had been the captain of King Zechariah’s army, led a counter revolt against King Shallum. King Menahem came from Tirzah, the old capital of Israel. He killed King Shallum in Samaria. For more information about the month reign of King Shallum, you can look it up in the lost “Book of the Annals of the Kings of Israel.” I do not know how much more is there. The new King Menahem got mad at Tappuah and then sacked killed people from Tirzah to Samaria. There were a couple of towns with the name of Tappuah. Joshua mentions Tappuah as between the borders of Ephraim and Manasseh. King Menahem also ripped open the wombs of the pregnant woman, a kind of ancient punishment. The prophets Amos and Hosea will wail against King Menahem.
