If a woman approaches any animal to mate with it, you must kill both the woman and the animal. They must surely be put to death; their blood is upon them.
Jewish Publication Society of America Version (JPS1917) - Leviticus 20:16 >And if a woman approach unto any beast, and lie down thereto, thou shalt kill the woman, and the beast: they shall surely be put to death; their blood shall be upon them.
