תלמוד על יבמות 13:6

If it was doubtful whether he jumped or the wind pushed him? Let us hear from the following: Rabban Simeon ben Gamliel says, if he fell down immediately, it is a bill of divorce; if he fell after some time it is no bill of divorce. But is “immediately” not a case of doubt whether he jumped or the wind pushed him? This implies that in case of doubt whether he jumped or the wind pushed him, it is a bill of divorce¹²⁷The different versions of the Tosephta seem to disagree with the Yerushalmi (the topic is not treated in the Babli). Tosephta 4:7 (Lieberman) “If a healthy person said, write a bill of divorce for my wife, climbed on a roof, and fell down, one writes and delivers as long as he still is alive. Rabban Simeon ben Gamliel says, if he jumped, it is a bill of divorce; if he fell down after some time, it is no bill of divorce since I may say that the wind pushed him.” Tosephta 6:9 (Zuckermandel): “If a healthy person said, write a bill of divorce for my wife, climbed on a roof, and fell down, one writes and delivers as long as he still is alive. If he fell down after some time, it is no bill of divorce since I may say that the wind pushed him.” Tosephta (quote of Rashba): “If a healthy person said, write a bill of divorce for my wife, climbed on a roof, and fell down, one writes but does not deliver since I may say that the wind pushed him.” A discussion of the different versions is in J. N. Epstein, ²מבוא לנוסח המשנה, p. 600–601..
