'Terrifying' in the Bible

Then the king’s face grew pale and his thoughts alarmed him, and his hip joints went slack and his knees began knocking together.

After this I kept looking in the night visions, and behold, a fourth beast, dreadful and terrifying and extremely strong; and it had large iron teeth. It devoured and crushed and trampled down the remainder with its feet; and it was different from all the beasts that were before it, and it had ten horns.
