אבל אם שמע וקיים או ששמע ושתק ומת ביום שלאחריו אין יכול להפר

but if he heard and confirmed it, or heard it and was silent, and died on the following day,<span class="x" onmousemove="('comment',' Having thus ipso facto confirmed it.

Now I might think that only if he had heard it in the husband's lifetime, and so could have annulled it together with him, does he inherit his authority, but if he had not heard of it in her husband's lifetime, his authority is not transmitted.
