Commentary for Kiddushin 69:7
ולר' יהודה דאמר שני כתובים הבאים כאחד מלמדין ותפילין מ"ע שלא הזמן גרמא מא"ל משום דהואי מצה שמחה והקהל שלשה כתובים הבאים כאחד ושלשה כתובים הבאים כאחד אין מלמדין
R'Meir. But he holds that there are two verses with the same teaching, and such do not illumine [others].<span class="x" onmousemove="('comment',' I.e, he does not employ the comparison, but deduces by analogy from pilgrimage, as above. Unleavened bread and 'assembling' do not furnish any opposite conclusion, for they are two verses with the same teaching.');"><sup>13</sup></span> But according to R'Judah, who maintains that two verses with the same teaching illumine [others], and [also] that phylacteries are a positive command limited to time, what can be said? - Because unleavened bread, rejoicing [on Festivals], and 'assembling' are three verses with the same teaching,<span class="x" onmousemove="('comment',' These are three positive commands limited to time and binding upon women.');"><sup>14</sup></span>
Daf Shevui to Kiddushin
The answer is that we have a third verse, the obligation to rejoice on festivals. R. Judah holds that they are obligated for this mitzvah as well. And since everyone holds that when three verses come as one do not teach, we now have no source to obligate women for positive time-bound commandments.
