Leviticus 20:13-15

New Catholic Bible

¹³ If a man has sex with another man, like one would have sex with a woman, both of them must be put to death. Their blood is upon their own heads. ¹⁴ It is lewd for a man to marry a woman and her mother. Both he and they are to be burned with fire so that there might not be any lewdness among you. ¹⁵ If a man has sex with an animal, he must die. You shall also slay the animal.
