Judges 1:18-21

18Judah's men also took for themselves the cities of Gaza, Ashkelon and Ekron, as well as the land around those cities.

19The Lord helped the men of Judah so that they took the towns in the hill country for themselves. But they could not win against the people who lived on the lower land near the sea. Those people had iron chariots to help them fight.

20Caleb received Hebron for his family, as Moses had promised him. Caleb had chased out the three clans of Anak who lived there.

21The men of Benjamin's tribe could not chase out the Jebusites who lived in Jerusalem. As a result, the Jebusites continue to live in Jerusalem with the people of Benjamin.
