Numbers 31:18-20

Darby Translation

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.

²⁰ And every garment, and every vessel of skin, and all work of goat's hair, and every utensil of wood shall ye purify.
