Jubilees 41
3And this Er, the first-born of Judah, was wicked, and the Lord slew him.
5And Onan knew that the seed would not be his, (but) his brother's only, and he went into the house of his brother's wife, and spilt the seed on the ground, and he was wicked in the eyes of the Lord, and He slew him.
7And he grew up; but Bedsu'el, the wife of Judah, did not permit her son Shelah to marry. And Bedsu'el, the wife of Judah, died in the fifth year of this week.
9And she put off her widow's clothes, and put on a veil, and adorned herself, and sat in the gate adjoining the way to Timnah.
10And as Judah was going along he found her, and thought her to be an harlot, and he said unto her: 'Let me come in unto thee'; and she said unto him Come in,' and he went in.
12And she said unto him 'Give them to me until thou dost send me my hire', and he said unto her: 'I will send unto thee a kid of the goats'; and he gave them to her, , and , she conceived by him.
13And Judah went unto his sheep, and she went to her father's house.
14And Judah sent a kid of the goats by the hand of his shepherd, an Adullamite, and he found her not; and he asked the people of the place, saying: 'Where is the harlot who was here' And they said unto him; 'There is no harlot here with us.'
15And he returned and informed him, and said unto him that he had not found her: 'I asked the people of the place, and they said unto me: "There is no harlot here." ' And he said: 'Let her keep (them) lest we become a cause of derision.'
16And when she had completed three months, it was manifest that she was with child, and they told Judah, saying: 'Behold Tamar, thy daughter-in-law, is with child by whoredom.'
17And Judah went to the house of her father, and said unto her father and her brothers: 'Bring her forth, and let them burn her, for she hath wrought uncleanness in Israel.'
18And it came to pass when they brought her forth to burn her that she sent to her father-in-law the ring and the necklace, and the staff, saying: 'Discern whose are these, for by him am I with child.'
19And Judah acknowledged, and said: 'Tamar is more righteous than I am. And therefore let them burn her not'
20And for that reason she was not given to Shelah, and he did not again approach her
23And Judah acknowledged that the deed which he had done was evil, for he had lain with his daughter-in-law, and he esteemed it hateful in his eyes, and he acknowledged that he had transgressed and gone astray, for he had uncovered the skirt of his son, and he began to lament and to supplicate before the Lord because of his transgression.
24And we told him in a dream that it was forgiven him because he supplicated earnestly, and lamented, and did not again commit it.
25And he received forgiveness because he turned from his sin and from his ignorance, for he transgressed greatly before our God; and every one that acts thus, every one who lies with his mother-in-law, let them burn him with fire that he may burn therein, for there is uncleanness and pollution upon them, with fire let them burn them.
26And do thou command the children of Israel that there be no uncleanness amongst them, for every one who lies with his daughter-in-law or with his mother-in-law hath wrought uncleanness; with fire let them burn the man who has lain with her, and likewise the woman, and He will turn away wrath and punishment from Israel.
27And unto Judah we said that his two sons had not lain with her, and for this reason his seed was stablished for a second generation, and would not be rooted out.
28For in singleness of eye he had gone and sought for punishment, namely, according to the judgment of Abraham, which he had commanded his sons, Judah had sought to burn her with fire.
