'Bodies' in the Bible

At the end of the ten days their appearance was better and their bodies were healthier than all the young men who had been eating the royal delicacies.

And the princes, governors, and captains, and the king's counsellers, being gathered together, saw these men, upon whose bodies the fire had no power, nor was an hair of their head singed, neither were their coats changed, nor the smell of fire had passed on them.

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