Fornication

Acts 15:20,29; Matthew 5:32; Matthew 19:9; 2 Chronicles 21:11,13; Isaiah 23:17; Ezekiel 16:15,26,29; Revelation 14:8; Revelation 17:2,4; Revelation 18:3,9
This was very common among the Gentiles, which accounts for its being mentioned in the message sent from the conference at Jerusalem to the Gentiles (Acts 15:20, 2920But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood. (Acts 15:20)
29That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well. (Acts 15:29)
); and its being so often prohibited in the epistles. The word is sometimes used where “adultery” is the sense (Matt. 5:3232But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery. (Matthew 5:32); Matt. 19:99And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery. (Matthew 19:9)). It often has in the O. T. a symbolical reference to the turning from God to idols (2 Chron. 21:11, 1311Moreover he made high places in the mountains of Judah, and caused the inhabitants of Jerusalem to commit fornication, and compelled Judah thereto. (2 Chronicles 21:11)
13But hast walked in the way of the kings of Israel, and hast made Judah and the inhabitants of Jerusalem to go a whoring, like to the whoredoms of the house of Ahab, and also hast slain thy brethren of thy father's house, which were better than thyself: (2 Chronicles 21:13)
; Isa. 23:1717And 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. (Isaiah 23:17); Ezek. 16:15, 26, 2915But thou didst trust in thine own beauty, and playedst the harlot because of thy renown, and pouredst out thy fornications on every one that passed by; his it was. (Ezekiel 16:15)
26Thou hast also committed fornication with the Egyptians thy neighbors, great of flesh; and hast increased thy whoredoms, to provoke me to anger. (Ezekiel 16:26)
29Thou hast moreover multiplied thy fornication in the land of Canaan unto Chaldea; and yet thou wast not satisfied herewith. (Ezekiel 16:29)
); and in the N. T. to unfaithful intercourse with Babylon, the mother of harlots (Rev. 14:88And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication. (Revelation 14:8); Rev. 17:2, 42With whom the kings of the earth have committed fornication, and the inhabitants of the earth have been made drunk with the wine of her fornication. (Revelation 17:2)
4And the woman was arrayed in purple and scarlet color, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication: (Revelation 17:4)
; Rev. 18:3, 93For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies. (Revelation 18:3)
9And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning, (Revelation 18:9)
).
