'Bondage' in the Bible

yet now our flesh is as the flesh of our brethren, our children as their children; and behold, we must bring into bondage our sons and our daughters to be servants, and some of our daughters are brought into bondage already; neither is it in the power of our hand to redeem them, for other men have our fields and our vineyards.

and refused to obey, neither were they mindful of thy wonders which thou hadst done among them; but hardened their neck, and in their rebellion made a captain to return to their bondage. But thou art a +God ready to forgive, gracious and merciful, slow to anger and of great loving-kindness, and thou forsookest them not.
