Judges 1:34-35

34The Amorites were too strong for the men of Dan's tribe. So Dan's people had to live in the hill country. The Amorites would not let them live in the low land.

35The Amorites were also strong enough to keep Mount Heres, Aijalon and Shaalbim for themselves. But when the Israelite army became stronger, they made the Amorites do hard work for them.
