'Men of War' in the Bible

Eleazar the priest said to the men of war who went to the battle, "This is the statute of the law which the LORD has commanded Moses:

Levy a tribute to the LORD of the men of war who went out to battle: one soul of five hundred; of the persons, of the cattle, of the donkeys, and of the flocks.

Now the prey, over and above the booty which the men of war took, was six hundred seventy-five thousand sheep,

and they said to Moses, "Your servants have taken the sum of the men of war who are under our command, and there lacks not one man of us.

(The men of war had taken booty, every man for himself.)
