'Mighty' in the Bible

"How great are his signs! How mighty are his wonders! His kingdom will last forever, and his authority continues from one generation to the next."

The king uttered these words: "Is this not the great Babylon that I have built for a royal residence by my own mighty strength and for my majestic honor?"

He will attack mighty fortresses, aided by a foreign deity. To those who recognize him he will grant considerable honor. He will place them in authority over many people, and he will parcel out land for a price.
