Matthew Poole and continuators on Daniel 7:20

20 And of the ten horns that were in his head , and of the other which came up, and before whom three fell, even of that horn that had eyes, and a mouth, that spake very great things, whose look was more stout than his fellows .

What they meant:

i. e. He had more power and more fierceness. This is wont to be interpreted of Antiochus, and the persecuting Emperours because it agrees well to them.
