'Terrible' in the Bible

"After these things, as I was watching in the night visions a fourth beast appeared -- one dreadful, terrible, and very strong. It had two large rows of iron teeth. It devoured and crushed, and anything that was left it trampled with its feet. It was different from all the beasts that came before it, and it had ten horns.

His power will be great, but it will not be by his strength alone. He will cause terrible destruction. He will be successful in what he undertakes. He will destroy powerful people and the people of the holy ones.
