'Untied' in the Bible

Because God has untied my tent cord and afflicted me, people throw off all restraint in my presence.

He answered, "But I see four men, untied and walking around in the midst of the fire! No harm has come to them! And the appearance of the fourth is like that of a god!"

So they went and found a colt tied at a door, outside in the street, and untied it.
