'Mightily' in the Bible

It paws the ground in the valley, exulting mightily, it goes out to meet the weapons.

Cry out and shout for joy, O citizens of Zion, for the Holy One of Israel acts mightily among you!"

"Then, Jeremiah, make the following prophecy against them: 'Like a lion about to attack, the Lord will roar from the heights of heaven; from his holy dwelling on high he will roar loudly. He will roar mightily against his land. He will shout in triumph like those stomping juice from the grapes against all those who live on the earth.
