'Men of War' in the Bible

So Moses instructed the people, "Muster your men of war to attack the Midianites and deliver the LORD'S vengeance against Midian.

And Eleazar the priest said unto the men of war which went to the battle, This is the ordinance of the law which the LORD commanded Moses;

And let division be made of it into two parts, one for the men of war who went out to the fight, and one for all the people:

And levy a tribute unto the LORD of the men of war which went out to battle: one soul of five hundred, both of the persons, and of the beeves, and of the asses, and of the sheep:

And the booty, being the rest of the prey which the men of war had caught, was six hundred thousand and seventy thousand and five thousand sheep,

And the other half of the children of Israel which Moses separated from the men of war

And they said unto Moses, Thy servants have taken the sum of the men of war which are under our charge, and there lacketh not one man of us.

(For the men of war had taken spoil, every man for himself.)
