Leviticus 18:22-24

CLV(i) 22 With a male you shall not lie as if going to bed with a woman. This is an abhorrence. 23 You shall not give your emission to any beast to be unclean with it. And a woman shall not stand before a beast to copulate with it. This is decadence. 24 Do not defile yourselves in any of these ways. For in all of these the nations which I am dismissing before your face are defiled.
