Joshua 16:8 Meaning and Commentary

Joshua 16:8

The border went out from Tappuah westward
Which was different from the Tappuah in the tribe of Judah, ( Joshua 15:34 ) ; this was in the tribe of Ephraim on the border of Manasseh, ( Joshua 17:8 ) ;

unto the river Kanah;
supposed by some to be the brook Cherith, by which Elijah hid himself, ( 1 Kings 17:3 1 Kings 17:5 ) ; though objected to by others; it seems to have had its name from the reeds which grew in it, or on the banks of it:

and the goings out thereof were at the sea;
if the river Kanah was the brook Cherith, this must be the dead or salt sea: but that is never called "the sea", rather the Mediterranean sea is meant, and consequently Kanah could not be Cherith, which was at too great a distance from this sea:

this [is] the inheritance of the tribe of the children of Ephraim by
their families;
that is, this is the description of the border of it; for the cities within are not mentioned, and the descriptions in general are very obscure.

Joshua 16:8 In-Context

6 and the border went out westward at Michmethath on the north; and the border turned about eastward to Taanath-shiloh, and passed along it on the east of Janoah;

7 and it went down from Janoah to Ataroth, and to Naarah, and reached to Jericho, and went out at the Jordan.

8 From Tappuah the border went along westward to the brook of Kanah; and the goings out of it were at the sea. This is the inheritance of the tribe of the children of Ephraim according to their families;

9 together with the cities which were set apart for the children of Ephraim in the midst of the inheritance of the children of Manasseh, all the cities with their villages.

10 They didn't drive out the Canaanites who lived in Gezer: but the Canaanites dwell in the midst of Ephraim to this day, and are become servants to do forced labor.
