Numbers 31:17-19

Common English Bible

¹⁷ Now kill every male child and every female who has known a man intimately by sleeping with him. ¹⁸ But all the young girls who have not known a man intimately by sleeping with him, spare for yourselves. ¹⁹ You will remain outside the camp for seven days. Everyone among you or your captives who has killed a person or touched a corpse must purify themselves on the third and seventh days.
