'Free' in the Bible

"I have aroused him in righteousness, and I'll make all his pathways smooth. It is he who will rebuild my city and set my exiles free, but not for a price nor reward, " says the LORD of the Heavenly Armies.

saying to captives, "Come out!' and to those who are in darkness, "Be free!' "They will feed on all the mountains, and their pasture will be on all the barren hills.

Distress will quickly be set free. He won't die in the Pit, nor will he lack food."

Isn't this the fast that I have been choosing: to loose the bonds of injustice, and to untie the cords of the yoke, and to let the oppressed go free, and to break every yoke?
