"15 And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast. 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."
Don't forget Leviticus 20:15 & 20:16 either.
"15 And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast. 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."
