Judges 1:23 (KJV)

Also Judah took Gaza with the coast thereof, and Askelon with the coast thereof, and Ekron with the coast thereof.

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.

And they gave Hebron unto Caleb, as Moses said: and he expelled thence the three sons of Anak.

And the children of Benjamin did not drive out the Jebusites that inhabited Jerusalem; but the Jebusites dwell with the children of Benjamin in Jerusalem unto this day.

And the house of Joseph, they also went up against Bethel: and the LORD was with them.

And the spies saw a man come forth out of the city, and they said unto him, Shew us, we pray thee, the entrance into the city, and we will shew thee mercy.

And when he shewed them the entrance into the city, they smote the city with the edge of the sword; but they let go the man and all his family.

And the man went into the land of the Hittites, and built a city, and called the name thereof Luz: which is the name thereof unto this day.

Neither did Manasseh drive out the inhabitants of Bethshean and her towns, nor Taanach and her towns, nor the inhabitants of Dor and her towns, nor the inhabitants of Ibleam and her towns, nor the inhabitants of Megiddo and her towns: but the Canaanites would dwell in that land.

And it came to pass, when Israel was strong, that they put the Canaanites to tribute, and did not utterly drive them out.
