Contradiction with Joshua 13:32
Joshua 13:32 claims to summarize territories given to the tribes in much larger terms, while Joshua 19:31 lists specific inheritance for Asher, creating a contradiction in territorial specificity.
Joshua 13:32: These [are the countries] which Moses did distribute for inheritance in the plains of Moab, on the other side Jordan, by Jericho, eastward.
Contradiction with Numbers 34:14
Numbers 34:14 details inheritance east of Jordan for Reuben, Gad, and half-tribe of Manasseh, contradicting the idea of westward allocation in Joshua 19:31.
Numbers 34:14: For the tribe of the children of Reuben according to the house of their fathers, and the tribe of the children of Gad according to the house of their fathers, have received [their inheritance]; and half the tribe of Manasseh have received their inheritance:
Contradiction with Judges 1:27
Judges 1:27 states that some tribes did not drive out the inhabitants fully, while Joshua 19:31 implies complete allocation and control over the territory.
Judges 1:27: Neither did Manasseh drive out [the inhabitants of] Bethshean and her towns, nor Taanach and her towns, nor the inhabitants of Dor and her towns, nor the inhabitants of Ibleam and her towns, nor the inhabitants of Megiddo and her towns: but the Canaanites would dwell in that land.
Contradiction with Joshua 17:18
Joshua 17:18 claims forest land for Manasseh, contradicting the extent or exclusivity of Asher's inheritance in Joshua 19:31.
Joshua 17:18: But the mountain shall be thine; for it [is] a wood, and thou shalt cut it down: and the outgoings of it shall be thine: for thou shalt drive out the Canaanites, though they have iron chariots, [and] though they [be] strong.
Contradiction with Joshua 14:2
Joshua 14:2 outlines inheritance by lot rather than prophetic designation, which might create a contradiction with the direct allocations mentioned in Joshua 19:31.
Joshua 14:2: By lot [was] their inheritance, as the LORD commanded by the hand of Moses, for the nine tribes, and [for] the half tribe.
