2 Kings 15:14-16

14Then Menahem son of Gadi marched up from Tirzah, reached Samaria, then struck down Shallum son of Jabesh in Samaria, killed him, and became king in his place.

15Now the rest of the acts of Shallum, including his conspiracy that he contrived, behold, they are written in the Book of the Chronicles of the Kings of Israel.

16Then Menahem struck down Tiphsah and all who were in it, and its territories from Tirzah, because they did not open to him, therefore he attacked it and ripped open all its pregnant women.
