Leviticus 18:22 (common translations): • ESV / NIV style: “You shall not lie with a male as with a woman; it is an abomination.”  • KJV: “Thou shalt not lie with mankind, as with womankind: it is abomination.” This is the clearest “plain and simple” statement matching what you’re asking for.  Leviticus 20:13 (the penalty verse): • ESV: “If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death; their blood is upon them.”  These are the primary Old Testament verses that directly address male same-sex acts in those terms. New Testament references The New Testament doesn’t use the exact same phrasing but refers to the same idea: • 1 Corinthians 6:9-10 (ESV): “…neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality… will inherit the kingdom of God.” 
(The Greek terms here are often linked back to the Leviticus prohibitions.) • Romans 1:26-27 also describes men abandoning “natural relations with women” and committing “shameless acts with men.” These are the straightforward verses on the topic. Different Bible translations vary slightly in wording (e.g., “abomination,” “detestable,” “abhorrence”), but the core meaning in the original Hebrew is consistent across major versions.
