Jubilees 33:1-23
1And Jacob went and lived to the south of Magdaladra'ef. He went to his father Isaac, he and Leah his wife, on the new moon of the tenth month.
2And Reuben saw Bilhah, Rachel's maid, the concubine of his father, bathing in water in a secret place, and he loved her.
3And he hid himself at night, and he entered the house of Bilhah at night, and he found her sleeping alone on a bed in her house.
4And he lay with her, and she awoke and saw, and behold, Reuben was lying with her in the bed; and she uncovered the border of her covering and seized him, and cried out, and discovered that it was Reuben.
5And she was ashamed because of him, and released her hand from him, and he fled.
6And she lamented exceedingly because of this thing, and did not tell it to anyone.
7And when Jacob returned and sought her, she said to him: 'I am not clean for you, for I have been defiled as regards you; for Reuben has defiled me, and has lain with me in the night, and I was asleep, and did not realize until he uncovered my skirt and slept with me.'
8And Jacob was exceedingly angry with Reuben because he had lain with Bilhah, because he had uncovered his father's skirt.
9And Jacob did not approach her again because Reuben had defiled her. And as for any man who uncovers his father's skirt, his deed is exceedingly wicked, for he is abominable before the Lord.
10For this reason it is written and ordained on the heavenly tablets that a man should not lie with his father's wife, and should not uncover his father's skirt, for this is unclean: they shall surely die together, the man who lies with his father's wife and the woman also, for they have committed uncleanness on the earth.
11And there shall be nothing unclean before our God in the nation which He has chosen for Himself as a possession.
12And again, it is written a second time: 'Cursed is he who lies with the wife of his father, for he has uncovered his father's shame'; and all the holy ones of the Lord said, 'So be it; so be it.'
13And you, Moses, command the children of Israel to observe this word; for it entails a punishment of death; and it is unclean, and there is no atonement forever to atone for the man who has committed this, but he is to be put to death and slain, and stoned with stones, and rooted out from the midst of the people of our God.
14For no man who does so in Israel is permitted to remain alive a single day on the earth, for he is abominable and unclean.
15And let them not say: to Reuben was granted life and forgiveness after he had lain with his father's concubine, and to her also, though she had a husband, and her husband Jacob, his father, was still alive.
16For until that time the ordinance and judgment and law had not been revealed in its completeness for all, but in your days it has been revealed as a law of seasons and of days, and an everlasting law for the everlasting generations.
17And for this law there is no completion of days, and no atonement for it, but they must both be rooted out in the midst of the nation: on the day when they committed it they shall slay them.
18And you, Moses, write it down for Israel that they may observe it, and act according to these words, and not commit a sin unto death; for the Lord our God is judge, who shows no partiality and accepts no gifts.
19And tell them these words of the covenant, that they may hear and observe, and be on their guard with respect to them, and not be destroyed and rooted out of the land; for an uncleanness, and an abomination, and a contamination, and a pollution are all who commit it on the earth before our God.
20And there is no greater sin than the fornication which they commit on earth; for Israel is a holy nation to the Lord its God, and a nation of inheritance, and a priestly and royal nation and His own possession; and no such uncleanness shall appear in the midst of the holy nation.
21And in the third year of this sixth week [2145 A.M.] Jacob and all his sons went and lived in the house of Abraham, near Isaac his father and Rebecca his mother.
22And these were the names of the sons of Jacob: the firstborn Reuben, Simeon, Levi, Judah, Issachar, Zebulun, the sons of Leah; and the sons of Rachel, Joseph and Benjamin; and the sons of Bilhah, Dan and Naphtali; and the sons of Zilpah, Gad and Asher; and Dinah, the daughter of Leah, the only daughter of Jacob.
23And they came and bowed themselves before Isaac and Rebecca, and when they saw them they blessed Jacob and all his sons, and Isaac rejoiced exceedingly, for he saw the sons of Jacob, his younger son, and he blessed them.
