Contradiction with Joshua 13:6
This verse promises that God will drive out the inhabitants of the land, while Joshua 19:33 specifies borders within the land, possibly implying coexistence.
Joshua 13:6: All the inhabitants of the hill country from Lebanon unto Misrephothmaim, [and] all the Sidonians, them will I drive out from before the children of Israel: only divide thou it by lot unto the Israelites for an inheritance, as I have commanded thee.
Contradiction with Genesis 15:18
Here, God promises Abraham a vast land from the river of Egypt to the great river, the Euphrates, as inheritance, contrasting the more limited scope of territory in Joshua 19:33.
Genesis 15:18: In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
Contradiction with Numbers 34:2
This verse outlines the boundaries of the entire land of Canaan for Israel, which could conflict with the specific tribal allocation in Joshua 19:33.
Numbers 34:2: Command the children of Israel, and say unto them, When ye come into the land of Canaan; (this [is] the land that shall fall unto you for an inheritance, [even] the land of Canaan with the coasts thereof:)
Contradiction with Deuteronomy 11:24
The verse suggests the boundaries of Israel extend from the wilderness to Lebanon, and from the Euphrates to the western sea, a broader claim than the delineation in Joshua 19:33.
Deuteronomy 11:24: Every place whereon the soles of your feet shall tread shall be yours: from the wilderness and Lebanon, from the river, the river Euphrates, even unto the uttermost sea shall your coast be.
