'Bodies' in the Bible

And the satraps, the prefects, the governors and the advisors of the king [were] assembling, [and] they saw these men, that the fire had no power over their bodies, and the hair of their heads was not singed, and their garments were not harmed, and the smell of fire did not come from them.

Nebuchadnezzar {responded}, saying, "Blessed be their God, [the God] of Shadrach, Meshach and Abednego, who sent his angel and rescued his servants who trusted in him, and the command of the king they disobeyed, and they gave their bodies so that they [did] not serve and [did] not worship any god except their God.
