'Mighty men' in the Bible

For behold, this day do I make thee a strong fenced town, an iron pillar, and a wall of steel against the whole land; against the kings and mighty men of Judah; against the priests and people of the land.

After that Nebuchadnezzar king of Babylon had led away captive Jechoniah the son of Jehoiakim king of Judah, and the mighty men also of Judah, with the workmasters, and cunning men of Jerusalem, unto Babylon. The LORD showed me a vision: Behold, there stood two mounds of figs before the Temple of the LORD.

They shall climb over the walls, and win the strongholds. Then the mighty men's hearts in Moab shall be like the heart of a woman travailing with child.
