Leviticus 18. It All Seems Pretty Clear. Old Testament.

 22 “‘Do not have sexual relations with a man as one does with a woman; that is detestable.

23 “‘Do not have sexual relations with an animal and defile yourself with it. A woman must not present herself to an animal to have sexual relations with it; that is a perversion.

24 “‘Do not defile yourselves in any of these ways, because this is how the nations that I am going to drive out before you became defiled. 25 Even the land was defiled; so I punished it for its sin, and the land vomited out its inhabitants. 26 But you must keep my decrees and my laws. The native-born and the foreigners residing among you must not do any of these detestable things, 27 for all these things were done by the people who lived in the land before you, and the land became defiled. 28 And if you defile the land, it will vomit you out as it vomited out the nations that were before you.

29 “‘Everyone who does any of these detestable things—such persons must be cut off from their people. 30 Keep my requirements and do not follow any of the detestable customs that were practiced before you came and do not defile yourselves with them. I am the Lord your God.’

Leviticus 24.

17 “‘Anyone who takes the life of a human being is to be put to death. 

NEW Testament 1 Corinthians 6.

9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men[a]
