Top 25 Bible Verses About Unmarried Sex (ESV)

4 Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.

7:1 Now concerning the matters about which you wrote: “It is good for a man not to have sexual relations with a woman.” 2 But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. 3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband. 4 For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.

6 Now as a concession, not a command, I say this. 7 I wish that all were as I myself am. But each has his own gift from God, one of one kind and one of another.

8 To the unmarried and the widows I say that it is good for them to remain single, as I am. 9 But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion.

10 To the married I give this charge (not I, but the Lord): the wife should not separate from her husband 11 (but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.

12 To the rest I say (I, not the Lord) that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her. 13 If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him. 14 For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but as it is, they are holy. 15 But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you to peace. 16 For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?

17 Only let each person lead the life that the Lord has assigned to him, and to which God has called him. This is my rule in all the churches. 18 Was anyone at the time of his call already circumcised? Let him not seek to remove the marks of circumcision. Was anyone at the time of his call uncircumcised? Let him not seek circumcision. 19 For neither circumcision counts for anything nor uncircumcision, but keeping the commandments of God. 20 Each one should remain in the condition in which he was called. 21 Were you a bondservant when called? Do not be concerned about it. (But if you can gain your freedom, avail yourself of the opportunity.) 22 For he who was called in the Lord as a bondservant is a freedman of the Lord. Likewise he who was free when called is a bondservant of Christ. 23 You were bought with a price; do not become bondservants of men. 24 So, brothers, in whatever condition each was called, there let him remain with God.

25 Now concerning the betrothed, I have no command from the Lord, but I give my judgment as one who by the Lord’s mercy is trustworthy. 26 I think that in view of the present distress it is good for a person to remain as he is. 27 Are you bound to a wife? Do not seek to be free. Are you free from a wife? Do not seek a wife. 28 But if you do marry, you have not sinned, and if a betrothed woman marries, she has not sinned. Yet those who marry will have worldly troubles, and I would spare you that. 29 This is what I mean, brothers: the appointed time has grown very short. From now on, let those who have wives live as though they had none, 30 and those who mourn as though they were not mourning, and those who rejoice as though they were not rejoicing, and those who buy as though they had no goods, 31 and those who deal with the world as though they had no dealings with it. For the present form of this world is passing away.

32 I want you to be free from anxieties. The unmarried man is anxious about the things of the Lord, how to please the Lord. 33 But the married man is anxious about worldly things, how to please his wife, 34 and his interests are divided. And the unmarried or betrothed woman is anxious about the things of the Lord, how to be holy in body and spirit. But the married woman is anxious about worldly things, how to please her husband. 35 I say this for your own benefit, not to lay any restraint upon you, but to promote good order and to secure your undivided devotion to the Lord.

36 If anyone thinks that he is not behaving properly toward his betrothed, if his passions are strong, and it has to be, let him do as he wishes: let them marry—it is no sin. 37 But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed, he will do well. 38 So then he who marries his betrothed does well, and he who refrains from marriage will do even better.

39 A wife is bound to her husband as long as he lives. But if her husband dies, she is free to be married to whom she wishes, only in the Lord. 40 Yet in my judgment she is happier if she remains as she is. And I think that I too have the Spirit of God.

5 Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry.

18 Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body.

3 But sexual immorality and all impurity or covetousness must not even be named among you, as is proper among saints.

5 For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God.

28 But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.

9 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 men who practice homosexuality, 10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.

19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality, 20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, 21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

21 I fear that when I come again my God may humble me before you, and I may have to mourn over many of those who sinned earlier and have not repented of the impurity, sexual immorality, and sensuality that they have practiced.

13 “Food is meant for the stomach and the stomach for food”—and God will destroy both one and the other. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. 14 And God raised the Lord and will also raise us up by his power. 15 Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? Never! 16 Or do you not know that he who is joined to a prostitute becomes one body with her? For, as it is written, “The two will become one flesh.” 17 But he who is joined to the Lord becomes one spirit with him. 18 Flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. 19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, 20 for you were bought with a price. So glorify God in your body.

3 For this is the will of God, your sanctification: that you abstain from sexual immorality;

9 And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.”

32 But I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery.

19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality,

24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.

9 I wrote to you in my letter not to associate with sexually immoral people—10 not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. 11 But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one.

26 For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; 27 and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.

28 And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. 29 They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips,

8 But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.”

21 For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery,

5:1   My son, be attentive to my wisdom;
    incline your ear to my understanding,
2   that you may keep discretion,
    and your lips may guard knowledge.
3   For the lips of a forbidden woman drip honey,
    and her speech is smoother than oil,
4   but in the end she is bitter as wormwood,
    sharp as a two-edged sword.
5   Her feet go down to death;
    her steps follow the path to Sheol;
6   she does not ponder the path of life;
    her ways wander, and she does not know it.
7   And now, O sons, listen to me,
    and do not depart from the words of my mouth.
8   Keep your way far from her,
    and do not go near the door of her house,
9   lest you give your honor to others
    and your years to the merciless,
10   lest strangers take their fill of your strength,
    and your labors go to the house of a foreigner,
11   and at the end of your life you groan,
    when your flesh and body are consumed,
12   and you say, “How I hated discipline,
    and my heart despised reproof!
13   I did not listen to the voice of my teachers
    or incline my ear to my instructors.
14   I am at the brink of utter ruin
    in the assembled congregation.”
15   Drink water from your own cistern,
    flowing water from your own well.
16   Should your springs be scattered abroad,
    streams of water in the streets?
17   Let them be for yourself alone,
    and not for strangers with you.
18   Let your fountain be blessed,
    and rejoice in the wife of your youth,
19     a lovely deer, a graceful doe.
  Let her breasts fill you at all times with delight;
    be intoxicated always in her love.
20   Why should you be intoxicated, my son, with a forbidden woman
    and embrace the bosom of an adulteress?
21   For a man’s ways are before the eyes of the LORD,
    and he ponders all his paths.
22   The iniquities of the wicked ensnare him,
    and he is held fast in the cords of his sin.
23   He dies for lack of discipline,
    and because of his great folly he is led astray.

7:1   My son, keep my words
    and treasure up my commandments with you;
2   keep my commandments and live;
    keep my teaching as the apple of your eye;
3   bind them on your fingers;
    write them on the tablet of your heart.
4   Say to wisdom, “You are my sister,”
    and call insight your intimate friend,
5   to keep you from the forbidden woman,
    from the adulteress with her smooth words.
6   For at the window of my house
    I have looked out through my lattice,
7   and I have seen among the simple,
    I have perceived among the youths,
    a young man lacking sense,
8   passing along the street near her corner,
    taking the road to her house
9   in the twilight, in the evening,
    at the time of night and darkness.
10   And behold, the woman meets him,
    dressed as a prostitute, wily of heart.
11   She is loud and wayward;
    her feet do not stay at home;
12   now in the street, now in the market,
    and at every corner she lies in wait.
13   She seizes him and kisses him,
    and with bold face she says to him,
14   “I had to offer sacrifices,
    and today I have paid my vows;
15   so now I have come out to meet you,
    to seek you eagerly, and I have found you.
16   I have spread my couch with coverings,
    colored linens from Egyptian linen;
17   I have perfumed my bed with myrrh,
    aloes, and cinnamon.
18   Come, let us take our fill of love till morning;
    let us delight ourselves with love.
19   For my husband is not at home;
    he has gone on a long journey;
20   he took a bag of money with him;
    at full moon he will come home.”
21   With much seductive speech she persuades him;
    with her smooth talk she compels him.
22   All at once he follows her,
    as an ox goes to the slaughter,
  or as a stag is caught fast
23     till an arrow pierces its liver;
  as a bird rushes into a snare;
    he does not know that it will cost him his life.
24   And now, O sons, listen to me,
    and be attentive to the words of my mouth.
25   Let not your heart turn aside to her ways;
    do not stray into her paths,
26   for many a victim has she laid low,
    and all her slain are a mighty throng.
27   Her house is the way to Sheol,
    going down to the chambers of death.

12   There is a way that seems right to a man,
    but its end is the way to death.

20 But if the thing is true, that evidence of virginity was not found in the young woman, 21 then they shall bring out the young woman to the door of her father’s house, and the men of her city shall stone her to death with stones, because she has done an outrageous thing in Israel by whoring in her father’s house. So you shall purge the evil from your midst.
