'Mighty' in the Bible

(for people will hear of your great name, your mighty acts, and your obvious power), when he comes and prays facing this Temple,

"Go out," he responded, "and stand on the mountain in the presence of the LORD." And there was the LORD, passing by! A tremendous, mighty windstorm was tearing at the mountains and breaking the rocks in pieces in the presence of the LORD, but the LORD was not in the windstorm. After the wind there came an earthquake, but the LORD was not in the earthquake.
