'Mighty' in the Bible

They run like mighty men; they climb the wall like men of war; and they march every one on his ways, and they break not their ranks.

Proclaim ye this among the nations; prepare war; stir up the mighty men; let all the men of war draw near, let them come up.

Haste ye, and come, all ye nations round about, and gather yourselves together: thither cause thy mighty ones to come down, O Jehovah.
