Rav Sheshet raised an objection from that which was taught in a baraita. With regard to the Temple candelabrum, it is stated: “Outside the veil of the testimony, in the Tent of Meeting, shall Aaron order it from evening to morning before the Lord continually; it shall be a statute forever throughout your generations” (Leviticus 24:3). It must be understood: And does God require its light for illumination at night? Didn’t the children of Israel, all forty years that they walked in the wilderness, walk exclusively by His light, the pillar of fire? Rather, the lighting of the candelabrum is testimony to mankind that the Divine Presence rests among Israel. The Gemara asks: What is this testimony? Rav said: That is the westernmost lamp in the candelabrum in which the measure of oil placed was the same measure of oil as was placed in the other lamps, and nevertheless he would light the others from it each day and with it he would conclude, i.e., the westernmost lamp would continue burning throughout the day after all the others were extinguished. The rest of the lamps burned only at night, and each night he would relight the rest of the lamps from the westernmost lamp. But isn’t it true that here, in the Temple, since the lamps were fixed in the candelabrum, it was impossible to light directly from lamp to lamp? There was no alternative to taking a wood chip and lighting the rest of the lamps from the westernmost lamp. Consequently, it is difficult both according to the one who said that one may not light from lamp to lamp due to contempt for the mitzva and according to the one who said that one may not light from lamp to lamp due to weakening the mitzva.
מֵתִיב רַב שֵׁשֶׁת: ״מִחוּץ לְפָרוֹכֶת הָעֵדוּת יַעֲרוֹךְ״, וְכִי לְאוֹרָהּ הוּא צָרִיךְ? וַהֲלֹא כׇּל אַרְבָּעִים שָׁנָה שֶׁהָלְכוּ בְנֵי יִשְׂרָאֵל בַּמִּדְבָּר לָא הָלְכוּ אֶלָּא לְאוֹרוֹ! אֶלָּא עֵדוּת הִיא לְבָאֵי עוֹלָם שֶׁהַשְּׁכִינָה שׁוֹרָה בְּיִשְׂרָאֵל. מַאי עֵדוּת? אָמַר רַב: זוֹ נֵר מַעֲרָבִי שֶׁנּוֹתֵן בָּהּ שֶׁמֶן כְּמִדַּת חַבְרוֹתֶיהָ, וּמִמֶּנָּה הָיָה מַדְלִיק וּבָהּ הָיָה מְסַיֵּים. וְהָא הָכָא כֵּיוָן דִּקְבִיעִי נֵרוֹת, לָא סַגְיָא דְּלָא מִשְׁקָל וְאַדְלוֹקֵי. קַשְׁיָא בֵּין לְמַאן דְּאָמַר מִשּׁוּם בִּזּוּי מִצְוָה, וּבֵין לְמַאן דְּאָמַר מִשּׁוּם אַכְחוֹשֵׁי מִצְוָה!
Aaron shall set them up in the Tent of Meeting outside the curtain of the Pact [to burn] from evening to morning before יהוה regularly; it is a law for all time throughout the ages.

You shall further instruct the Israelites to bring you clear oil of beaten olives for lighting, for kindling lamps regularly.
