'Mightily' in the Bible

Therefore prophesy thou against them all these words, and say unto them, The LORD shall roar from on high, and utter his voice from his holy habitation; he shall mightily roar upon his habitation; he shall give a shout, as they that tread the grapes, against all the inhabitants of the earth.

Flee, bemoan mightily, go deep to dwell, Ye inhabitants of Hazor -- an affirmation of Jehovah, For given counsel against you hath Nebuchadrezzar king of Babylon, Yea, he deviseth against them a device.
