Judges 1:27-28: 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
This verse states that much land remains to be possessed, while Joshua 18:9 suggests a systematic allotment of land as though it had all been accounted for.

Contradiction with Joshua 23:4
