Deuteronomy 22:25 Kabbalah

וְֽאִם־בַּשָּׂדֶ֞ה יִמְצָ֣א הָאִ֗ישׁ אֶת־הנער [הַֽנַּעֲרָה֙] הַמְאֹ֣רָשָׂ֔ה וְהֶחֱזִֽיק־בָּ֥הּ הָאִ֖ישׁ וְשָׁכַ֣ב עִמָּ֑הּ וּמֵ֗ת הָאִ֛ישׁ אֲשֶׁר־שָׁכַ֥ב עִמָּ֖הּ לְבַדּֽוֹ׃

But if the man find the damsel that is betrothed in the field, and the man take hold of her, and lie with her; then the man only that lay with her shall die.
