2 Kings 15:13-15

13In the thirty-ninth year of Judah’s King Uzziah, Shallum son of Jabesh became king; he reigned in Samaria a full month.

14Then Menahem son of Gadi came up from Tirzah to Samaria and struck down Shallum son of Jabesh there. He killed him and became king in his place.

15As for the rest of the events of Shallum’s reign, along with the conspiracy that he formed, they are written in the Historical Record of Israel’s Kings.
