Judges 1:28

When Israel was strong they put the Canaanites to tribute Herein they violated the law, whereby they were enjoined to destroy or expel that people when they were able. And as they were strong enough to impose tribute on them, they undoubtedly might have driven them entirely out of the land. But it cost them less trouble, and brought them more profit, to make them tributaries, than to expel them; and therefore they preferred it, being influenced by sloth and covetousness. And this seems to be here spoken of as their common fault at this time.
