Romans 1:24, 26-27
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompense of their error which was meet.
Ephesians 5:3-4
3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints;
4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks.
Proverbs 7:5, 21-22
5 That they may keep thee from the strange woman, from the stranger which flattereth with her words.
21 With her much fair speech she caused him to yield, with the flattering of her lips she forced him.
22 He goeth after her straightway, as an ox goeth to the slaughter, or as a fool to the correction of the stocks;
Leviticus 18:1-21
1 And the LORD spake unto Moses, saying,
2 Speak unto the children of Israel, and say unto them, I am the LORD your God.
3 After the doings of the land of Egypt, wherein ye dwelt, shall ye not do: and after the doings of the land of Canaan, whither I bring you, shall ye not do: neither shall ye walk in their ordinances.
4 Ye shall do my judgments, and keep mine ordinances, to walk therein: I am the LORD your God.
5 Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them: I am the LORD.
6 None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD.
7 The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness.
8 The nakedness of thy father's wife shalt thou not uncover: it is thy father's nakedness.
9 The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.
10 The nakedness of thy son's daughter, or of thy daughter's daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.
11 The nakedness of thy father's wife's daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
12 Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman.
13 Thou shalt not uncover the nakedness of thy mother's sister; for she is thy mother's near kinswoman.
14 Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt.
15 Thou shalt not uncover the nakedness of thy daughter in law: she is thy son's wife; thou shalt not uncover her nakedness.
16 Thou shalt not uncover the nakedness of thy brother's wife: it is thy brother's nakedness.
17 Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.
18 Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
19 Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness.
20 Moreover thou shalt not lie carnally with thy neighbour's wife, to defile thyself with her.
21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD.
Malachi 2:11-12
11 Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of the LORD which he loved, and hath married the daughter of a strange god.
12 The LORD will cut off the man that doeth this, the master and the scholar, out of the tabernacles of Jacob, and him that offereth an offering unto the LORD of hosts.
Proverbs 7:24-27
24 Hearken unto me now therefore, O ye children, and attend to the words of my mouth.
25 Let not thine heart decline to her ways, go not astray in her paths.
26 For she hath cast down many wounded: yea, many strong men have been slain by her.
27 Her house is the way to hell, going down to the chambers of death.
1 Corinthians 7:7-9
7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
8 I say therefore to the unmarried and widows, It is good for them if they abide even as I.
9 But if they cannot contain, let them marry: for it is better to marry than to burn.
Proverbs 23:30-33
30 They that tarry long at the wine; they that go to seek mixed wine.
31 Look not thou upon the wine when it is red, when it giveth his colour in the cup, when it moveth itself aright.
32 At the last it biteth like a serpent, and stingeth like an adder.
33 Thine eyes shall behold strange women, and thine heart shall utter perverse things.
Ezekiel 23:14-16
14 And that she increased her whoredoms: for when she saw men portrayed upon the wall, the images of the Chaldeans portrayed with vermilion,
15 Girded with girdles upon their loins, exceeding in dyed attire upon their heads, all of them princes to look to, after the manner of the Babylonians of Chaldea, the land of their nativity:
16 And as soon as she saw them with her eyes, she doted upon them, and sent messengers unto them into Chaldea.
Isaiah 23:15-17
15 And it shall come to pass in that day, that Tyre shall be forgotten seventy years, according to the days of one king: after the end of seventy years shall Tyre sing as an harlot.
16 Take an harp, go about the city, thou harlot that hast been forgotten; make sweet melody, sing many songs, that thou mayest be remembered.
17 And it shall come to pass after the end of seventy years, that the LORD will visit Tyre, and she shall turn to her hire, and shall commit fornication with all the kingdoms of the world upon the face of the earth.
