Two ketubot, one get and one death, she can collect two ketubot. A get, a ketubah and a death—if the get is from before the ketubah, she can collect two ketubot; if the ketubah is from before the get, she can only collect one ketubah, for [it must be that] the one who divorced her took her back and took her back with the understanding that the first ketubah [remained in place]. (The following omitted in the printed edition, supplied from Ehrfurt manuscript:) If she wrote a receipt for him [for her whole ketubah] while they were married, he divorced her, took her back and died—she takes her ketubah of 100 zuz [the minimum for a non-virgin from the 2nd marriage]. If he made a new [ketubah], she takes whatever is in the new [ketubah].
