4:16 Let his heart be changed, etc: It does not appear by scripture that Nabuchodonosor was changed from human shape; much less that he was changed into an ox; but only that he lost his reason, and became mad; and in this condition remained abroad in the company of beasts, eating grass like an ox, till his hair grew in such manner as to resemble the feathers of eagles, and his nails to be like birds' claws.
