'Bodies' in the Bible

The satraps, the deputies, and the governors, and the king's counselors, being gathered together, saw these men, that the fire had no power on their bodies, nor was the hair of their head singed, neither were their pants changed, nor had the smell of fire passed on them.

Nebuchadnezzar spoke and said, Blessed be the God of Shadrach, Meshach, and Abednego, who has sent his angel, and delivered his servants who trusted in him, and have changed the king's word, and have yielded their bodies, that they might not serve nor worship any god, except their own God.
