Leviticus 20:14-16

Amplified Bible

¹⁴ It is immoral and shameful if a man marries a woman and her mother; all three shall be burned in fire, so that there will be no immorality among you.^{(A) 15} If a man has intimate relations with an animal, he shall most certainly be put to death; you shall kill the animal also. ¹⁶ If a woman approaches any animal to mate with it, you shall kill the woman and the animal; they shall most certainly be put to death; their blood is on them.
