'Terribleness' in the Bible

and Jehovah brought us forth out of Egypt with a mighty hand, and with an outstretched arm, and with great terribleness, and with signs, and with wonders;

As for thy terribleness, the pride of thy heart hath deceived thee, O thou that dwellest in the clefts of the rock, that holdest the height of the hill: though thou shouldest make thy nest as high as the eagle, I will bring thee down from thence, saith Jehovah.
