'Trousers' in the Bible

So these men, in their trousers, robes, head coverings, and other clothes, were tied up and thrown into 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.
