Leviticus 19:19-20

19My statutes shall ye observe. Thou shalt not let thy cattle gender with another sort; thou shalt not sow thy field with seed of two sorts; and a garment woven of two materials shall not come upon thee.

20And if a man lie with a woman for copulation, and she is a bondwoman betrothed to a husband, but not at all ransomed, nor hath freedom been given to her, there shall be a chastisement: they shall not be put to death, for she was not free.
