'Terrifying' in the Bible

“My king, as you were watching, a colossal statue appeared. That statue, tall and dazzling, was standing in front of you, and its appearance was terrifying.

“Then I wanted to know the true meaning of the fourth beast, the one different from all the others, extremely terrifying, with iron teeth and bronze claws, devouring, crushing, and trampling with its feet whatever was left.
