'Pants' in the Bible

As the deer pants for the water brooks, so my soul pants after you, God.

Then these men were bound in their pants, their tunics, and their mantles, and their [other] garments, and were cast into the midst of the burning fiery furnace.

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.
