Judges 1:28-30

28 When Israel became strong, they put the Canaanites to forced labor, but they did not drive them out.

29 Nor did Ephraim drive out the Canaanites who were living in Gezer, so the Canaanites settled in Gezer among them.

30 Nor did Zebulun drive out the inhabitants of Kitron, or the inhabitants of Nahalol, so the Canaanites settled among them, but became subject to forced labor.
