'Labor' in the Bible

When Israel became stronger, they made the Canaanites serve as forced labor but never drove them out completely.

Zebulun failed to drive out the residents of Kitron or the residents of Nahalol, so the Canaanites lived among them and served as forced labor.

Naphtali did not drive out the residents of Beth-shemesh or the residents of Beth-anath. They lived among the Canaanites who were living in the land, but the residents of Beth-shemesh and Beth-anath served as their forced labor.

The Amorites refused to leave Har-heres, Aijalon, and Shaalbim. When the house of Joseph got the upper hand, the Amorites were made to serve as forced labor.
