Joshua 17:8 Meaning and Commentary

Joshua 17:8

[Now] Manasseh had the land of Tappuah
The whole territory that went by that name, from a city of note in it, next mentioned; all the fields and villages in it belonged to the tribe of Manasseh:

but Tappuah on the border of Manasseh [belonged] to the children of
Ephraim;
and was one of those separate cities they had among the inheritance of the children of Manasseh; though it seems they had only the city, not the territory adjacent to it, and which was named from it.

Joshua 17:8 In-Context

6 For the daughters of the sons of Manasse inherited a portion in the midst of their brethren, and the land of Galaad was assigned to the remainder of the sons of Manasse.
7 And the borders of the sons of Manasse were Delanath, which is before the sons of Anath, and it proceeds to the borders to Jamin and Jassib to the fountain of Thaphthoth.
8 It shall belong to Manasse, and Thapheth on the borders of Manasse to the sons of Ephraim.
9 And the borders shall go down to the valley of Carana southward by the valley of Jariel, ( a turpentine tree to Ephraim between the city of Manasse:) and the borders of Manasse northward to the brook; and the sea shall be its termination.
10 Southward to Ephraim, and northward to Manasse; and the sea shall be their cost; and northward they shall border upon Aseb, and eastward upon Issachar.
