Deuteronomy 22:25-27

25“However, if the man finds the girl who is engaged (legally betrothed) in the [open] field, and seizes her and is intimate with her [by force], then only the man who lies with her shall be put to death.

26But you shall do nothing to the young woman; she has committed no sin worthy of death, for this is the same as when a man attacks his neighbor and murders him.

27When he found her in the [open] field, the engaged girl [may have] cried out for help, but there was no one to [hear and] save her.
