After this I saw in the night visions, and behold a fourth beast, dreadful and terrible, and strong exceedingly; and it had great iron teeth; it devoured and broke in pieces, and stamped the residue with its feet; and it was diverse from all the beasts that were before it; and it had ten horns.
Rashi on Daniel
in the visions of the night on another night. The first three he saw on one night, and this one on another night, because it is equal to them all. In Leviticus Rabbah (13:5).
