Those passages are:
Leviticus 18:22 – You shall not sleep with a male as one sleeps with a female; it is an abomination.
Leviticus 20:13 – If there is a man who sleeps with a male as those who sleep with a woman, both of them have committed a detestable act; they must be put to death. They have brought their own deaths upon themselves.
Romans 1:26-27 – For this reason God gave them over to degrading passions; for their women exchanged natural relations for that which is contrary to nature, and likewise the men, too, abandoned natural relations with women and burned in their desire toward one another, males with males committing shameful acts and receiving in their own persons the due penalty of their error.
1 Corinthians 6:9-10 – Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the sexually immoral, nor idolaters, nor adulterers, nor homosexuals, nor thieves, nor the greedy, nor those habitually drunk, nor verbal abusers, nor swindlers, will inherit the kingdom of God.
1 Timothy 1:9-10
