'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 break not their ranks.

Proclaim this among the nations: prepare war, arouse 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.
