'Slaves' in the Bible

Javan (Greece), Tubal and Meshech (Asia Minor) traded with you; with the lives of men [taken as slaves] and vessels of bronze they paid for your merchandise.

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.
