2 Kings 15:14

For Menahem the son of Gadi went up from Tirzah
A city in the tribe of Manasseh, the royal city of the kings of Israel before Omri, of which (See Gill on Joshua 12:24), whether Menahem was of this city, or was now besieging it with an army he had the command of, as Josephus ^F18 suggests, is not certain; however, hearing what had befallen Zachariah, he came from hence: and came to Samaria; which, according to Bunting ^F19, was six miles from Tirzah:

and smote Shallum the son of Jabesh in Samaria, and slew him, and
reigned in his stead;
judging he had as good a right to the throne as Shallum had.
