'Ass's' in the Bible

Knotting his ass's cord to the vine, and his young ass to the best vine; washing his robe in wine, and his clothing in the blood of grapes:

And Samson said, With a red ass's mouth-bone I have made them red with blood, with a red ass's mouth-bone I have sent destruction on a thousand men.

And they became very short of food in Samaria; for they kept it shut in till the price of an ass's head was eighty shekels of silver, and a small measure of doves' droppings was five shekels of silver.
