Numbers 31:18

But all the women children, that have not known a man by lying with him, keep alive for yourselves.

But all the girls, who have not known man by lying with him, keep alive for yourselves.

But all the women-children, that have not known man by lying with him, keep alive for yourselves.

and all the infants among the women, who have not known the lying of a male, ye have kept alive for yourselves.

but spare for yourselves every girl who has never had relations with a man.
