Reference for Leviticus 19:20

וְ֠אִישׁ כִּֽי־יִשְׁכַּ֨ב אֶת־אִשָּׁ֜ה שִׁכְבַת־זֶ֗רַע וְהִ֤וא שִׁפְחָה֙ נֶחֱרֶ֣פֶת לְאִ֔ישׁ וְהָפְדֵּה֙ לֹ֣א נִפְדָּ֔תָה א֥וֹ חֻפְשָׁ֖ה לֹ֣א נִתַּן־לָ֑הּ בִּקֹּ֧רֶת תִּהְיֶ֛ה לֹ֥א יוּמְת֖וּ כִּי־לֹ֥א חֻפָּֽשָׁה׃

And whosoever lieth carnally with a woman, that is a bondmaid, designated for a man, and not at all redeemed, nor was freedom given her; there shall be inquisition; they shall not be put to death, because she was not free.
