Testament of Reuben 5:5
Testament of the Twelve PatriarchsFor moreover, concerning them, the angel of the Lord told me, and taught me, that women are overcome by the spirit of fornication more than men, and in their heart they plot against men; and by means of their adornment they deceive first their minds, and by the glance of the eye instill the poison, and then through the accomplished act they take them captive. For a woman cannot force a man openly, but by a harlot's bearing she beguiles him. Flee, therefore, fornication, my children, and command your wives and your daughters, that they adorn not their heads and faces to deceive the mind: because every woman who useth these wiles hath been reserved for eternal punishment. For thus they allured the Watchers who were before the flood; for as these continually beheld them, they lusted after them, and they conceived the act in their mind; for they changed themselves into the shape of men, and appeared to them when they were with their husbands.
1 Corinthians 6:18
15 Do you not know that your bodies are members of Christ? Should I take the members of Christ and make them members of a prostitute? Never! 16 Or do you not know that anyone who is united with a prostitute is one body with her? For it is said, “The two will become one flesh.” 17 But the one united with the Lord is one spirit with him. 18 Flee sexual immorality! “Every sin a person commits is outside of the body”—but the immoral person sins against his own body. 19 Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20 For you were bought at a price. Therefore glorify God with your body.
Notes and References
"... What is the origin or inspiration in 1 Corinthians 6:8, the central injunction of Paul's parenesis against going to prostitutes? Two answers to this question have been suggested. Whereas F. Godet and F. F. Bruce claim that the command may recall Joseph's literal fleeing from Potiphar's wife, the margin of Nestle-Aland notes the parallel of the Testament of Reuben 5:5. This short study investigates these two proposals and suggests that they may in fact both be right. The question of whether Paul quoted from non-canonical Jewish literature has long been debated. R. H. Charles's Apocrypha and Pseudepigrapha of the Old Testament (Oxford, 1913) claims that Pauline parallels can be found in Tobit (1. 199), Wisdom (1. 526 f), Enoch (2. 163 f), Letter of Aristeas (2. 92), 4 Ezra (2. 559) and especially the Testaments of the Twelve Patriarchs (2. 292), a document he claims was Paul's vade mecum. However, E. E. Ellis and others are skeptical of such parallels, and claim that only similar phraseology is represented ('Paul's use of non-canonical Jewish literature is very doubtful at best in no case has a direct use of writings of the diaspora been established'). The relation of 1 Corinthians 6:18 to the Testament of Reuben 5:5 is largely ignored in this debate, and by commentators on 1 Corinthians. Apparently the repetition of a mere three words has not impressed scholars, who, if aware of the parallel, usually put them down to coincidence. Hans Conzelmann rightly calls 'a characteristic catchword in parenesis', and there is certainly nothing distinctive about the term for sexual immorality in question ..."
