Judges 1:18-21

18Judah also captured Gaza with its territory, and Ashkelon with its territory, and Ekron with its territory.

19And the Lord was with Judah, and he took possession of the hill country, but he could not drive out the inhabitants of the plain because they had chariots of iron.

20And Hebron was given to Caleb, as Moses had said. And he drove out from it the three sons of Anak.

21But the people of Benjamin did not drive out the Jebusites who lived in Jerusalem, so the Jebusites have lived with the people of Benjamin in Jerusalem to this day.
