'Horribly' in the Bible

‘All the inhabitants of the coastlandsAre aghast and appalled at you,And their kings are horribly frightened and shudder;Their faces twitch and pale.

I will make many peoples appalled at you [at your judgment and your defeat], and their kings will be horribly afraid of you when I brandish My sword [of judgment] before them; they will tremble and shudder every moment, every man for his own life, on the day of your downfall.”
