Contradiction with Judges 1:19
Judges 1:19 states that the LORD was with Judah, implying a divine support that did not drive out all inhabitants due to chariots of iron, contrasting Joshua 2:21 that implies the LORD ceased driving out any nations at all.

Contradiction with Joshua 23:5
Joshua 23:5 reassures that the LORD will drive these nations out, which contradicts Judges 2:21 where God states He will no longer drive out these nations.
Joshua 23:5: And the LORD your God, he shall expel them from before you, and drive them from out of your sight; and ye shall possess their land, as the LORD your God hath promised unto you.

The LORD assures of a gradual removal of nations, differing from Judges 2:21 where the LORD ceases to drive them out.
Exodus 23:29-30: I will not drive them out from before thee in one year; lest the land become desolate, and the beast of the field multiply against thee.
Contradiction with Judges 3:1-2

One possible contradiction in that verse could involve the idea of a just and compassionate deity allowing or causing suffering.
