Jamieson-Fausset-Brown on Numbers 31:19
abide without the camp seven days: whosoever hath killed any person . . . purify both yourselves and your captives--Though the Israelites had taken the field in obedience to the command of God, they had become defiled by contact with the dead.

Moses, by now extending the ceremony of expiation to lawful homicide, intimates how carefully we ought to abstain from shedding human blood. It was required of the Israelites that they should strenuously advance through the midst of carnage; but, inasmuch as it is in a manner contrary to the order of nature that men should be killed by men, as if they were raging against their own bowels, God would have some vestiges of humanity preserved even in just punishments, so as to put a restraint upon all cruelty in the abstract.
