‘ And the man went into the land of the Hittites, and built a city and called its name Luz, which is its name to this day.'
The man left Canaan with his family and reaching the land of the Hittites built a new city, calling it Luz, possibly as a kind of guilt offering for what he had done. The Hittites, as a once powerful nation, dwelt in Syria, and their empire would shortly collapse.
In all this the tribes of Joseph, (Ephraim and Manasseh), were obedient to God's command to drive out the Canaanites. But this would soon change. Does the change from Joseph to Ephraim and Manasseh indicate the idea of covenant unfaithfulness resulting in division? Or that simply they divided up to go after their selected territories, or in order to make up ‘the twelve' once Levi had received Yahweh as their inheritance (Joshua 13:33).
