'Horribly' in the Bible

Be astonished, O ye heavens, at this, and be horribly afraid, be ye very desolate, saith the LORD.

Yea, I will make many people amazed at thee, and their kings shall be horribly afraid for thee, when I shall brandish my sword before them; and they shall tremble at every moment, every man for his own life, in the day of thy fall.
