Numbers 31:32

And the booty, being the rest of the prey... — The reference may be to the residue of the captives after the slaughter of all the males and of a large number of the women, and to the cattle which were brought to the camp, some, it may be, having been lost or slaughtered for food; or it may be to the booty which had been taken in captives and animals, as distinguished from the gold and silver, &c.
