'Free' in the Bible

I have raised him up in righteousness,and will level all roads for him.He will rebuild My city,and set My exiles free,not for a price or a bribe,”says the Lord of Hosts.

The prisoner is soon to be set free;he will not die and go to the Pit,and his food will not be lacking.

Isn’t the fast I choose:To break the chains of wickedness,to untie the ropes of the yoke,to set the oppressed free,and to tear off every yoke?
