Jubilees 3:31
29 He dismissed from the Garden of Eden all the animate beings that were in the Garden of Eden. All animate beings were dispersed — each by its kind and each by its nature — into the places which had been created for them. 30 But of all the animals and cattle he permitted Adam alone to cover his shame. 31 For this reason it has been commanded in the heavenly tablets regarding all those who know the judgment of the law that they cover their shame and not uncover themselves as the nations uncover themselves. 32 At the beginning of the fourth month Adam and his wife departed from the Garden of Eden. They lived in the land of Elda, in the land where they were created.
Pseudo Jonathan Genesis 6:2
1 When the children of men began to multiply on the face of the earth, and beautiful daughters were born to them. 2 The sons of the great ones saw that the daughters of men were beautiful, that they painted their eyes and put on rouge, and walked about with naked flesh. They conceived lustful thoughts, and they took wives to themselves from among all who pleased them. 3 The Lord said in his Memra, 'None of the evil generations that are to arise (in the future) will be judged according to the order of judgment applied to the generation of the Flood, (that is) to be destroyed and wiped out from the world. Did I not put my holy spirit in them that they might perform good deeds? But behold, their deeds are evil. Behold, I gave them an extension of a hundred and twenty years that they might repent, but they have not done so.'
Notes and References
"... Particularly in the gymnasium the “curious” feature of Judean ethnic identity became all too visible – the circumcision of the male foreskin, since exercises were conducted in the nude. Some Judeans underwent an epispasm by which the foreskin was restored, and so was said to have forsaken the “holy covenant” (1 Maccabees 1:15). No wonder the gymnasium was regarded as one of the most important abominations of Hellenism (1 Maccabees 1:14-15; 2 Maccabees 4:9-17). Jubilees 3:31 also says Adam and Eve covered their genitals, unlike the Gentiles. According to Cohen, there are passages in the Tanak that speak of the importance of circumcision (Jeremiah 9:24-25; Genesis 17, 34; Exodus 4:24-26, 12:43-49; Joshua 5:2-11) but the Bible “as a whole generally ignores it and nowhere regards it as the essential mark of [Judean] identity or as the sine qua non for membership in the [Judean polity]. It attained this status only in Maccabean times” ..."
