Contradiction with Joshua 11:23
Joshua 11:23 mentions that Joshua took the whole land, which seems to contradict Joshua 13:3 that lists territories not yet conquered.
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 Judges 3:1-2
Judges 3:1-2 indicates that some nations were deliberately left unconquered to test Israel, which contradicts the idea of remaining unconquered lands in Joshua 13:3 due to incompletion.
Judges 3:1-2: Now these [are] the nations which the LORD left, to prove Israel by them, [even] as many [of Israel] as had not known all the wars of Canaan;
Paradox #1
There could be a contradiction regarding the territories described. The verse mentions specific regions that were to be conquered, but historically, it's unclear if these areas were ever fully controlled by the Israelites as described, leading to possible inconsistencies between the biblical account and archaeological findings.
