Numbers 31:17-19

Darby Translation

¹⁷ And now slay every male among the little ones, and slay every woman that hath known man by lying with him,

¹⁸ but all the children among the women that have not known lying with a man, keep alive for yourselves.

¹⁹ And encamp outside the camp seven days; whoever hath killed a person, and whoever hath touched any slain; ye shall purify yourselves on the third day, and on the seventh day, you and your captives.
