'Slaves' in the Bible

So take note, I am about to make you slaves of the tribes of the east. They will make camps among you and pitch their tents among you. They will eat your fruit and drink your milk.

Javan, Tubal, and Meshech were your merchants. They exchanged slaves and bronze utensils for your goods.

Also the tree of the field will yield its fruit and the earth will yield its produce; and My people will be secure on their land. Then they will know [with confidence] that I am the Lord, when I have broken the bars of their yoke and have rescued them from the hand of those who made them slaves.
