Numbers 31:18-20

New Revised Standard Version Catholic Edition

¹⁸ But all the young girls who have not known a man by sleeping with him, keep alive for yourselves. ¹⁹ Camp outside the camp seven days; whoever of you has killed any person or touched a corpse, purify yourselves and your captives on the third and on the seventh day. ²⁰ You shall purify every garment, every article of skin, everything made of goats’ hair, and every article of wood.”
