'Labor' in the Bible

{And then} if {they accept your terms of peace} and {they surrender to you}, {and then} all the people {inhabiting it} shall be forced labor for you, and they shall serve you.

And the Egyptians treated us badly, and they oppressed us and imposed on us hard labor.

A people that you do not know shall consume the harvest of your land and all your labor, and you will be only oppressed and crushed {for the rest of your lives}.
