וַיִּפְרֹ֤שׂ אֶת־הָאֹ֙הֶל֙ עַל־הַמִּשְׁכָּ֔ן וַיָּ֜שֶׂם אֶת־מִכְסֵ֥ה הָאֹ֛הֶל עָלָ֖יו מִלְמָ֑עְלָה כַּאֲשֶׁ֛ר צִוָּ֥ה יְהוָ֖ה אֶת־מֹשֶֽׁה׃ (ס)
또 성막 위에 막을 펴고 그 위에 덮개를 덮으니 여호와께서 모세에게 명하신 대로 되니라
Mishnah Shabbat
Whatever comes from a tree they may not light [the Shabbat light] except for flax. And whatever comes from a tree cannot be defiled with tent-uncleanness except linen. A wick made of cloth which was twisted but not singed: Rabbi Eliezer says: it is unclean, and one may not light with it; Rabbi Akiva says: it is clean and one may light with it.
