Contradiction with Joshua 11:23
Joshua 11:23 states that Joshua took the whole land, which contradicts Joshua 17:7 where it implies an incomplete conquest regarding the territories of Manasseh.
Joshua 11:23: So Joshua took the whole land, according to all that the LORD said unto Moses; and Joshua gave it for an inheritance unto Israel according to their divisions by their tribes. And the land rested from war.
Contradiction with Joshua 13:13
Joshua 13:13 mentions the Israelites did not drive out the people of Geshur and Maacah, contrasting with Joshua 17:7's implication of territorial control.
Joshua 13:13: Nevertheless the children of Israel expelled not the Geshurites, nor the Maachathites: but the Geshurites and the Maachathites dwell among the Israelites until this day.
Contradiction with Joshua 15:63
While Joshua 17:7 outlines the land boundaries for Manasseh, Joshua 15:63 indicates that the Jebusites were not driven out, contradicting complete possession.
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
This verse explicitly mentions the tribe of Manasseh failing to drive out the inhabitants of certain cities, which contradicts any notion of complete possession in Joshua 17:7.
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 13:1
States there was very much land yet to be possessed, contradicting any implications of the completion in territorial assignments like in Joshua 17:7.
Joshua 13:1: Now Joshua was old [and] stricken in years; and the LORD said unto him, Thou art old [and] stricken in years, and there remaineth yet very much land to be possessed. [to...: Heb. to possess it]
