Two wives and כתובת בנין דכרין: lessons from the משנה, רב אשי's challenges, and the תנאים who argue about one wife dying in the husband's lifetime and one after his death

Overview

The גמרא first finishes a point about the משנה's wording: the first clause also uses the word 'precedes.' It then draws three lessons from the משנה's case of a man who married a first wife and then a second. First, the first wife's sons get כתובת בנין דכרין even when one wife died in his lifetime and the other after his death. Second, one wife's כתובה can count as the needed surplus for the other. Third, כתובת בנין דכרין cannot be collected from liened property. רב אשי pushes off the first two lessons by reading the משנה differently. The גמרא then shows that the case of one wife dying in his lifetime and one after his death is argued by the תנאים בן ננס and רבי עקיבא. רבה reports that the רבנן of בי רב saw their argument as being about surplus, and he adds that everyone agrees a creditor's payment counts as surplus. רב יוסף objects from רבי עקיבא's own words and goes back to the first explanation. He then links it to an argument between the תנא קמא and רבי שמעון in a ברייתא; the גמרא begins to push that link off, and the thought continues on the next amud.
