'Mighty men' in the Bible

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 didn't stay there in the land.

And he carried away all Jerusalem, and all the princes, and all the mighty men of valour, ten thousand captives, and all the craftsmen and smiths: none remained but the poorest sort of the people of the land.

Nebuchadnezzar led Jehoiachin away into exile to Babylon; also he took the king’s mother and the king’s wives and his officials and the leading men of the land [including Ezekiel] as exiles from Jerusalem to Babylon.

and all the men of valour seven thousand, and the artificers and the smiths a thousand, the whole are mighty men, warriors; and the king of Babylon bringeth them in a captivity to Babylon.
