2 Kings 15:14-17

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.

16At that time Menahem, starting from Tirzah, attacked Tiphsah and everyone in its vicinity, because they would not open their gates. So he attacked Tiphsah and ripped open all the pregnant women.

17In the thirty-ninth year of Azariah’s reign over Judah, Menahem son of Gadi became king of Israel, and he reigned in Samaria ten years.
