Numbers 31:17-19

Wycliffe Bible

¹⁷ And therefore slay ye all the men, whatever is of male kind, and the little children (And so kill ye all the men, yea, whoever is a male, and all the little children); and strangle ye the women that have known men fleshly;

¹⁸ soothly keep ye to you the young damsels, and all women virgins, (but you can keep for yourselves the young girls, and all the women who still be virgins,)

¹⁹ and dwell ye without the tents seven days. He that slayeth a man, or toucheth a slain man, shall be cleansed in the third [day], and the seventh day; (and then stay ye away from the tents for seven days. He who killeth a man, or toucheth a dead man, must cleanse both himself, and his captives, on the third day, and on the seventh day;)
