'Trousers' in the Bible

And the priest is to put on his linen robes and his linen trousers, and take up what is over of the offering after it has been burned on the altar, and put it by the side of the altar.

Let him put on the holy linen coat, and the linen trousers on his body, and the linen band round him, and the linen head-dress on his head; for this is holy clothing, and before he puts them on his body is to be washed with water.
