2 Kings 15:14-17

14Then Menahem the son of Gadi came up from Tirzah and came to Samaria, and he struck down Shallum the son of Jabesh in Samaria and put him to death and reigned in his place.

15Now the rest of the deeds of Shallum, and the conspiracy that he made, behold, they are written in the Book of the Chronicles of the Kings of Israel.

16At that time Menahem sacked Tiphsah and all who were in it and its territory from Tirzah on, because they did not open it to him. Therefore he sacked it, and he ripped open all the women in it who were pregnant.

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