'Horribly' in the Bible

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

All the inhabitants of the isles are astonished at thee, and their kings are horribly afraid; they are troubled in their countenance.

Yea, I will make many peoples 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.
