'Dreadful' in the Bible

After this I saw in the night visions, and behold a fourth beast, dreadful and terrible, and strong exceedingly; and it had great iron teeth: it devoured and brake in pieces, and stamped the residue with the feet of it: and it was diverse from all the beasts that were before it; and it had ten horns.

Then I would know the truth of the fourth beast, which was diverse from all the others, exceeding dreadful, whose teeth were of iron, and his nails of brass; which devoured, brake in pieces, and stamped the residue with his feet;

And I prayed unto the LORD my God, and made my confession, and said, O Lord, the great and dreadful God, keeping the covenant and mercy to them that love him, and to them that keep his commandments;

And He has carried out completely His [threatening] words which He had spoken against us and against our rulers [the kings, princes, and judges] who ruled us, to bring on us a great tragedy; for under the whole heaven there has not been done anything [so dreadful] like that which [He commanded and] was done to Jerusalem.
