'Frightful' in the Bible

The oracle of [the] wilderness of [the] sea: As storm winds passing over in the Negev, {it comes} from [the] desert, from a frightful land.

A drought [will come] against her waters, and they will dry up, for it [is] a land of images, and because of the frightful [objects], they act like madmen.

After this in the visions of the night I was looking and there was a fourth beast, terrifying and frightful and exceedingly strong, and {it had} {great iron teeth}, [and it was] devouring and crushing, and it stamped the remainder with its feet; and it was different from all [the other] beasts {that preceded it} {and it had ten horns}.
