What the Bible says about sexual purity

Proverbs 5:1-23

My son, pay attention to my wisdom. Turn your ear to my understanding: that you may maintain discretion, that your lips may preserve knowledge. For the lips of an adulteress drip honey. Her mouth is smoother than oil, but in the end she is as bitter as wormwood, and as sharp as a two-edged sword. Her feet go down to death. Her steps lead straight to Sheol. She gives no thought to the way of life. Her ways are crooked, and she doesn’t know it. Now therefore, my sons, listen to me. Don’t depart from the words of my mouth. Remove your way far from her. Don’t come near the door of her house, lest you give your honor to others, and your years to the cruel one; lest strangers feast on your wealth, and your labors enrich another man’s house. You will groan at your latter end, when your flesh and your body are consumed, and say, “How I have hated instruction, and my heart despised reproof; neither have I obeyed the voice of my teachers, nor turned my ear to those who instructed me! I have come to the brink of utter ruin, among the gathered assembly.” Drink water out of your own cistern, running water out of your own well. Should your springs overflow in the streets, streams of water in the public squares? Let them be for yourself alone, not for strangers with you. Let your spring be blessed. Rejoice in the wife of your youth. A loving doe and a graceful deer— let her breasts satisfy you at all times. Be captivated always with her love. For why should you, my son, be captivated with an adulteress? Why embrace the bosom of another? For the ways of man are before Yahweh’s eyes. He examines all his paths. The evil deeds of the wicked ensnare him. The cords of his sin hold him firmly. He will die for lack of instruction. In the greatness of his folly, he will go astray.

2 Timothy 2:22

Flee from youthful lusts; but pursue righteousness, faith, love, and peace with those who call on the Lord out of a pure heart.

Ephesians 5:1-3

Be therefore imitators of God, as beloved children. Walk in love, even as Christ also loved you, and gave himself up for us, an offering and a sacrifice to God for a sweet-smelling fragrance. But sexual immorality, and all uncleanness, or covetousness, let it not even be mentioned among you, as becomes saints;

Colossians 3:5-6

Put to death therefore your members which are on the earth: sexual immorality, uncleanness, depraved passion, evil desire, and covetousness, which is idolatry; for which things’ sake the wrath of God comes on the children of disobedience.

1 Peter 1:14-16

as children of obedience, not conforming yourselves according to your former lusts as in your ignorance, but just as he who called you is holy, you yourselves also be holy in all of your behavior; because it is written, “You shall be holy; for I am holy.”

Hebrews 13:4

Let marriage be held in honor among all, and let the bed be undefiled: but God will judge the sexually immoral and adulterers.

Song of Solomon 2:7

I adjure you, daughters of Jerusalem, by the roes, or by the hinds of the field, that you not stir up, nor awaken love, until it so desires.

Romans 6:12-14

Therefore don’t let sin reign in your mortal body, that you should obey it in its lusts. Also, do not present your members to sin as instruments of unrighteousness, but present yourselves to God, as alive from the dead, and your members as instruments of righteousness to God. For sin will not have dominion over you. For you are not under law, but under grace.
