'Unbound' in the Bible

"As for the diseased person who has the infection, his clothes must be torn, the hair of his head must be unbound, he must cover his mustache, and he must call out 'Unclean! Unclean!'

{He answered}, saying, "Look, I see four men unbound walking in the midst of the fire and there is no damage to them, and the appearance of the fourth [man] resembles the son of a god."

But on the next day, wanting to know the real reason why Paul was being accused by the Jews, he released him and ordered the chief priests and the whole Council (Sanhedrin, Jewish High Court) to assemble; and brought Paul down and presented him before them.
