2 Kings 15:14-17

14Then Menahem the son of Gadi went up from 1Tirzah and came to Samaria, and struck Shallum son of Jabesh in Samaria, and killed him and became king in his place. 15Now as for the rest of the acts of Shallum and his conspiracy which he formed, behold, they are written in the Book of the Chronicles of the Kings of Israel. 16Then Menahem attacked Tiphsah and all who were in it and its borders from Tirzah, because they did not open up to him; so he attacked it and ripped up 2all its women who were pregnant.

17In the 3thirty-ninth year of Azariah king of Judah, Menahem the son of Gadi became king over Israel and reigned for ten years in Samaria.
