Contradiction with Joshua 11:23
Claims that Joshua took the whole land, which contradicts Joshua 15:15 where Caleb continues to conquer territories.
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 1:19
States that Judah could not drive out the inhabitants of the valley because they had iron chariots, in contrast with Joshua 15:15 where Caleb is seen succeeding in driving out the inhabitants.
Judges 1:19: And the LORD was with Judah; and he drave out [the inhabitants of] the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron. [drave...: or, possessed the mountain]
Contradiction with Judges 1:10
Describes the conquest over Hebron, but attributes it to the tribe of Judah rather than to Caleb, contradicting Joshua 15:15 where Caleb himself is involved in the conquest.
Judges 1:10: And Judah went against the Canaanites that dwelt in Hebron: (now the name of Hebron before [was] Kirjatharba:) and they slew Sheshai, and Ahiman, and Talmai.
Contradiction with Joshua 14:12
Caleb asks Joshua for Hebron, which implies Hebron still needed to be conquered, conflicting with the notion in 15:15, which suggests it was already under Caleb’s control.
Joshua 14:12: Now therefore give me this mountain, whereof the LORD spake in that day; for thou heardest in that day how the Anakims [were] there, and [that] the cities [were] great [and] fenced: if so be the LORD [will be] with me, then I shall be able to drive them out, as the LORD said.
