'Mighty men' in the Bible

Abijah began the battle with an army of brave soldiers, 400,000 chosen men. Jeroboam drew up in battle formation against him with 800,000 chosen men, valiant men.

Now Asa had an army of 300,000 men from Judah, who carried large shields and spears, and 280,000 from Benjamin, who carried shields and drew bows, all courageous men.

He had large supplies in the cities of Judah, and soldiers, courageous men, in Jerusalem.

This was the number of them by their fathers’ (ancestors’) households: of Judah, the commanders of thousands, Adnah the commander, and with him 300,000 courageous men;

and next to him Amasiah the son of Zichri, who volunteered for the Lord, and with him 200,000 courageous men;

He also hired 100,000 brave warriors from Israel for a hundred talents of silver.

The total number of the heads of the fathers’ households, of valiant men, was 2,600.

he decided, together with his officers and his soldiers, to stop up the water [supply] from the springs which were outside the city [by enclosing them with masonry and concealing them], and they helped him.
