Judges 1:33-35

33 The people of Naphtali did not make the people leave the cities of Beth Shemesh and Beth Anath. So the people of Naphtali continued to live with the Canaanites in those cities. Those people worked as slaves for the people of Naphtali.

34 The Amorites forced the Danites back into the mountains. The Amorites would not let them come down to live in the plain.

35 The Amorites were determined to stay in Mount Heres, Aijalon and Shaalbim. But the Israelites grew stronger. Then they made the Amorites work as slaves for them.
