Ephesians 5
³But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people. ⁴Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. ⁵For of this you can be sure: No immoral, impure or greedy person--such a man is an idolater--has any inheritance in the kingdom of Christ and of God. ⁶Let no one deceive you with empty words, for because of such things God's wrath comes on those who are disobedient. ⁷Therefore do not be partners with them.

1 Thessalonians 4
³It is God's will that you should be sanctified: that you should avoid sexual immorality; ⁴that each of you should learn to control his own body in a way that is holy and honorable, ⁵not in passionate lust like the heathen, who do not know God; ⁶and that in this matter no one should wrong his brother or take advantage of him. The Lord will punish men for all such sins, as we have already told you and warned you. ⁷For God did not call us to be impure, but to live a holy life.

Hebrews 12
¹⁶See that no one is sexually immoral, or is godless like Esau, who for a single meal sold his inheritance rights as the oldest son.

Hebrews 13
⁴Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.

Matthew 5
Adultery
²⁷"You have heard that it was said, 'Do not commit adultery.'  ²⁸But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.

Proverbs 6
²⁴ keeping you from the immoral woman, from the smooth tongue of the wayward wife.

Galatians 5
¹⁹The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; ²⁰idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions ²¹and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.

1 Corinthians 5
⁹I have written you in my letter not to associate with sexually immoral people-- ¹⁰not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. ¹¹But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.

1 Corinthians 6
⁹Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders ¹⁰nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. ¹¹And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
Sexual Immorality
¹²"Everything is permissible for me"--but not everything is beneficial. "Everything is permissible for me"--but I will not be mastered by anything. ¹³"Food for the stomach and the stomach for food"--but God will destroy them both. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. ¹⁴By his power God raised the Lord from the dead, and he will raise us also. ¹⁵Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never! ¹⁶Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, "The two will become one flesh." ¹⁷But he who unites himself with the Lord is one with him in spirit.  ¹⁸Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. ¹⁹Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own;

1 Corinthians 7
²But since there is so much immorality, each man should have his own wife, and each woman her own husband. ³The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. ⁴The wife's body does not belong to her alone but also to her husband. In the same way, the husband's body does not belong to him alone but also to his wife. ⁵Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. ⁶I say this as a concession, not as a command. ⁷I wish that all men were as I am. But each man has his own gift from God; one has this gift, another has that.  ⁸Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I am. ⁹But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.

2 Peter 2
⁹if this is so, then the Lord knows how to rescue godly men from trials and to hold the unrighteous for the day of judgment, while continuing their punishment.

1 Corinthians 10
¹³No temptation has seized you except what is common to man. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it.

Revelation 21
⁸But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars--their place will be in the fiery lake of burning sulfur. This is the second death."

Revelation 22
¹⁵Outside are the dogs, those who practice magic arts, the sexually immoral, the murderers, the idolaters and everyone who loves and practices falsehood.
