'Trousers' in the Bible

Then these men were tied up in their trousers, their coats, their caps and their other clothes, and were cast into the midst of the furnace of blazing fire.

The satraps, the prefects, the governors and the king’s high officials gathered around and saw in regard to these men that the fire had no effect on the bodies of these men nor was the hair of their head singed, nor were their trousers damaged, nor had the smell of fire even come upon them.
