[If a man said:] “This is your get if I die,” “This is your get if I die from this illness of mine,” [or] “This is your get after [my] death,” he has not said anything.  [If he said:] “[The get should take effect] from today if I die,” [or] “from now if I die,” it is a get; “from today and after [my death],” it is a get and not a get. If he dies, she performs chalitzah, but not yibum.  [If he said:] “This is your get from today if I die from this illness of mine,” and then he rose and went in the marketplace, and became ill and died, we assess him: if he died from his first illness, it is a get; if not, it is not a get.
