'Mighty' in the Bible

The watchmen of Nineveh shout: "An enemy who will scatter you is marching out to attack you!" "Guard the rampart! Watch the road! Prepare yourselves for battle! Muster your mighty strength!"

The shield of his mighty men is made red, the valiant men are in scarlet: the chariots shall be with flaming torches in the day of his preparation, and the fir trees shall be terribly shaken.
