'Mighty' in the Bible

and the kings of the earth, and the great men, and the rich, and the chiefs of thousands, and the mighty, and every servant, and every freeman, hid themselves in the dens, and in the rocks of the mountains,

and there came voices, and thunders, and lightnings; and a great earthquake came, such as came not since men came upon the earth, so mighty an earthquake -- so great!

and I heard as the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, 'Alleluia! because reign did the Lord God -- the Almighty!
