Talmud sur Ta'anit 2:12

What is the difference between these and those⁴⁷Between the disqualified women married to priests who receive Ketubah at the time of divorce and the secondarily prohibited who do not.? Since these are words of the Torah and the words of the Torah do not need support, therefore they have Ketubah. Those, because they are words of the Sopherim and the words of the Sopherim need support, therefore they do not have Ketubah. Some want to say since these are punished together with the child, they did not fine them, therefore they have Ketubah. Those, since they are not punished together with the child, they fined them, therefore they do not have Ketubah⁴⁸A more detailed discussion is in Tosephta 2:4/Babli 85b. Both these sources stress that a disqualified woman has no reason to seek out a Cohen since her child will be desecrated whereas a secondarily forbidden (who might be permitted to him by another sect) might want to be married by a relative. What is the difference between them? He who remarried his divorced wife after she had remarried⁴⁹This case is not discussed in the parallel sources.. For him who says since these are words of the Torah, and this case is a word of the Torah, therefore she has Ketubah. For those who want to say since these are punished together with the child, this one, since neither she nor the child is punished, therefore, she has no Ketubah.
