'Men of War' in the Bible

"Wherefore do ye think thus, 'We are mighty, and strong men of war'?

Hear, therefore: her young men shall fall in the streets, and all her men of war shall be taken away in that time, sayeth the LORD of Hosts.

Therefore shall her young men fall down in the streets, and all her men of war shall be rooted out in that day, sayeth the LORD.

He took out of the city a chamberlain which was a captain of the soldiers, and seven men that were the king's servants, which were found in the city; and Sepher, a captain that used to muster the men of war; with sixty men of the country that were taken in the city.
