Sanhedrin 87B

דין בתו מאנוסתו.

For example: the halakha of the prohibition against having sex with one’s daughter born from the victim of his rape.

דאמר רבא: אמר לי רב יצחק בר אבודימי, אתיא ״הנה״ ״הנה״,

As Rava says: Rav Yitzḥak bar Avudimi said to me: This prohibition is derived by means of a verbal analogy between the word henna, in the verse: “The nakedness of your son’s daughter, or of your daughter’s daughter, even their nakedness you should not uncover; for theirs [henna] is your own nakedness” (Leviticus 18:10), and the word henna in a different verse: “You should not uncover the nakedness of a woman and her daughter; you should not take her son’s daughter, or her daughter’s daughter, to uncover her nakedness: They [henna] are near kinswomen; it is lewdness” (Leviticus 18:17). This verbal analogy indicates that just as sex with one’s granddaughter and with one’s wife’s daughter or granddaughter is forbidden, so too, sex with one’s daughter is prohibited.

אתיא ״זמה״ ״זמה״.

Furthermore, it is derived from a verbal analogy between the word “lewdness” (Leviticus 18:17) and the word “lewdness” in the verse: “And if a man take with his wife also her mother, it is lewdness; they should be burned with fire, both he and they, so that there be no lewdness among you” (Leviticus 20:14), that one who has sex with his daughter or granddaughter is liable to be executed by burning.

״בין דם לדם״⁠ – בין דם נדה, דם לידה, דם זיבה. דם נדה ⁠– בפלוגתא עקביא בן מהללאל ורבנן, דתנן: דם הירוק ⁠– עקביא בן מהללאל מטמא, וחכמים מטהרין.

“Between blood and blood”; this is the ability to discern between the disparate halakhot relevant to the blood of menstruation, the blood of childbirth, and the blood of a gonorrhea-like discharge [ziva]. In each of these cases, there is a dispute between the rabbis with regard to a matter for whose intentional violation one is liable to receive karet. In the case of the blood of menstruation, it is with regard to the issue that is the subject of the dispute between Akavya ben Mahalalel and the Rabbis, as we learned in a Mishnah (Nidda 19a): With regard to blood that is green that is discharged by a woman, Akavya ben Mahalalel deems it blood of menstruation and impure, and the Rabbis deem it pure. According to Akavya ben Mahalalel, one who has sex with a woman who discharged green blood is liable to receive karet, while according to the Rabbis, he is exempt.
