Contradiction with Judges 1:8
Contrary to Judges 1:11 where Jerusalem was not fully captured, Judges 1:8 claims the children of Judah had already taken Jerusalem.
Judges 1:8: Now the children of Judah had fought against Jerusalem, and had taken it, and smitten it with the edge of the sword, and set the city on fire.
Contradiction with Joshua 15:63
This verse states that the children of Judah could not drive out the Jebusites from Jerusalem, suggesting they occupied it alongside the Jebusites, which contradicts Judges 1:11 on possessing cities completely.
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 2 Samuel 5:6-7
Describes King David's conquest of Jerusalem, implying it wasn't conquered in Judges 1 time, in contradiction with any implication that Judah controlled these areas.
2 Samuel 5:6-7: And the king and his men went to Jerusalem unto the Jebusites, the inhabitants of the land: which spake unto David, saying, Except thou take away the blind and the lame, thou shalt not come in hither: thinking, David cannot come in hither. [thinking...: or, saying David shall not, etc]
