'Mighty men' in the Bible

And Menahem took the silver from Israel, from all the mighty men of wealth (fifty shekels of silver from each man) to give to the king of Assyria. And the king of Assyria turned back and did not stay there in the land.

And he carried away all Jerusalem, and all the leaders, and all the mighty men of war, ten thousand captives, and all the craftsmen and smiths. None remained except the poorest sort of the people of the land.
