'Donkeys' in the Bible

So Moses took his wife [Zipporah] and his sons [Gershom and Eliezer] and seated them on donkeys, and returned to the land of Egypt. Moses also took the staff of God in his hand.

now hear this: the hand of the Lord will fall on your livestock which are out in the field, on the horses, the donkeys, the camels, the herds, and the flocks—a horrible plague shall come.
