2 Kings 15:13-15

13In the thirty-ninth year of Uzziah’s1 reign over Judah, Shallum son of Jabesh became king, and he reigned in Samaria one full month.

14Then Menahem son of Gadi went up from Tirzah to Samaria, struck down and killed Shallum son of Jabesh, and reigned in his place.

15As for the rest of the acts of Shallum, along with the conspiracy he led, they are indeed written in the Book of the Chronicles of the Kings of Israel.
