Contradiction with Joshua 15:63
Joshua 17:5 states that additional land was given to Manasseh, suggesting the successful conquest, while Joshua 15:63 notes the Jebusites could not be driven out by the children of Judah, implying incomplete conquest.
Joshua 15:63: As for the Jebusites the inhabitants of Jerusalem, the children of Judah could not drive them out: but the Jebusites dwell with the children of Judah at Jerusalem unto this day.
Contradiction with Judges 1:27
Joshua 17:5 indicates land was apportioned to Manasseh, while Judges 1:27 notes that Manasseh did not fully drive out the inhabitants of some towns, contradicting the notion of complete control.
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 Numbers 26:54
Joshua 17:5 gives specific territory to Manasseh, contradicting with Numbers 26:54, which speaks to allocation based on population size, potentially implying different land distributions.
Numbers 26:54: To many thou shalt give the more inheritance, and to few thou shalt give the less inheritance: to every one shall his inheritance be given according to those that were numbered of him. [give the more...: Heb. multiply his inheritance] [give the less...: Heb. diminish his inheritance]
