Judges 1:21 But the sons of Benjamin did not drive out the Jebusites who lived in Jerusalem; so the Jebusites have lived with the sons of Benjamin in Jerusalem to this day.

Judges 1:27 But Manasseh did not take possession of Beth-shean and its villages, or Taanach and its villages, or the inhabitants of Dor and its villages, or the inhabitants of Ibleam and its villages, or the inhabitants of Megiddo and its villages; so the Canaanites persisted in living in that land.
