וכבתה אין זקוק לה ורמינהו מצותה משתשקע החמה עד שתכלה רגל מן השוק מאי לאו דאי כבתה הדר מדליק לה לא דאי לא אדליק מדליק ואי נמי לשיעורה:
With regard to the opinion that one need not rekindle the Hanukkah light if it is extinguished, the Gemara asks: And is it true that if the Hanukkah light is extinguished one is not bound to attend to it? The Gemara raises a contradiction from that which was taught in a baraita: The mitzva of kindling the Hanukkah lights is from sunset until traffic in the marketplace ceases. Does that not mean that if the light is extinguished, he must rekindle it so that it will remain lit for the duration of that period? The Gemara answers: No, the baraita can be understood otherwise: That if one did not yet light at sunset, he may still light the Hanukkah lights until traffic ceases. Alternatively, one could say that this is referring to the matter of its measure. One must prepare a wick and oil sufficient to burn for the period lasting from sunset until traffic ceases. If he did so, even if the light is extinguished beforehand, he need not relight it.
