“And do ye abide without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify both yourselves and your captives on the third day, and on the seventh day.”
King James Version (KJV)
31:17 The little ones - Which they were forbidden to do to other people, #Deu 20:14|, except the Canaanites, to whom this people had equaled themselves by their horrid crimes, and therefore it is not strange, nor unjust, that God, the supreme Lord of all mens lives, who as he gives them, so may take them away when he pleaseth, did equal them in the punishment. Every woman - Partly for punishment, because the guilt was general, and though some of them only did prostitute themselves to the Israelites, yet the rest made themselves accessary by their consent or approbation; and partly, for prevention of the like mischief from such an adulterous generation.
31:20 Your raiment - Namely, your spoil and prey. All work - All which had contracted some ceremonial uncleanness either from the dead bodies which wore them, or the tents or houses where they were, in which such dead bodies lay, or from the touch of the Israelitish soldiers, who were legally defiled by the slaughters they made.
