Numbers 31:18-20

Amplified Bible

¹⁸ But all the young girls who have not known a man intimately, keep alive for yourselves [to marry]. ¹⁹ Camp outside the camp for seven days; whoever has killed any person and whoever has touched any dead body, purify yourselves and your captives, on the third day and on the seventh day. ²⁰ You shall purify every garment and every article made of leather and all the things made of goats’ hair, and every article made of wood.”
