The border of Manasseh was from Asher to Michmethath, which is before Shechem; and the border went along to the right hand, to the inhabitants of En Tappuah.
"Taanach, the modern Tel Taannak, guards a pass over Mount Carmel. Israel defeated the king of this place; but Manasseh, the tribe to which it was assigned, was not able to occupy it.  It was one of the Levitical cities  (Joshua 21:25), and finally occupied by Isaachar.  The mention of Taanach ahead of Megiddo here may indicate that at this time Megiddo was of less importance."[13]
