'Mighty men' in the Bible

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

And he carried away all Jerusalem, and all the generals, and all the mighty men of valour, ten thousand becoming captives, and all the artificers and the smiths, - none remained save the poorest of the people of the land.
