Leviticus 19:19-20

19Ye shall keep my statutes. Thou shalt not let thy cattle breed with another kind: thou shalt not sow thy field with mixed seed: neither shall a garment of linen and woollen woven together come upon thee. 20And whoever lieth carnally with a woman, that is a slave, betrothed to an husband, and not at all redeemed, nor freedom given her; she shall be scourged; they shall not be put to death, because she was not free.12
