Numbers 31:11

ויקחו את כל השלל AND THEY TOOK ALL THE SPOIL…[AND THEY BROUGHT IT TO MOSES] — This tells us that they were pious and righteous men and were not suspected of robbery by stretching out their hand against the spoil without permission, for it is said, “they took all the spoil … [and brought it to Moses]” (Sifrei Bamidbar 157:5). About them it is expressed in the traditional literature (Songs 6:6): “They teeth are like a flock of ewes … [whereof all are perfect]’ — i.e., even thy soldiers are all righteous (see Rashi Songs 4:2) שלל are movables consisting of clothing and ornaments. בז is booty of movables that are not ornaments. מלקוח are men and cattle, but in any passage where שבי is written in association with מלקוח, the term שבי applies to men and מלקוח to cattle alone.

And they took all the spoil, and all the prey, both of men and of beasts.
