'Mighty men' in the Bible

And Menahem exacted the money of Israel, even of all the mighty men of wealth, of each man fifty shekels of silver, to give to the king of Assyria. So the king of Assyria turned back, and stayed not there in the land.

And he carried away all Jerusalem, and all the princes, and all the mighty men of valor, even ten thousand captives, and all the artificers, and smiths: none remained, save the poorest sort of the people of the land.
