'Ass's' in the Bible

He bindeth his foal to the vine, And his ass's colt to the choice vine; He washeth his dress in wine, And his garment in the blood of grapes.

And there was a great famine in Samaria; and behold, they besieged it, until an ass's head was worth eighty silver-pieces, and the fourth part of a cab of dove's dung five silver-pieces.
