"The spirit of man is the lamp of the Lord." A Baraita taught that they used the High Priest's worn-out trousers to make the wicks of the Temple Menorah and the worn-out trousers of ordinary priests for candelabra outside the Temple. Reading the words "to cause a lamp to burn continually" in , Rabbi Samuel bar Isaac deduced that the unusual word , lehaalot, literally "to cause to ascend," meant that the wick had to allow the flame to ascend by itself. And thus the Rabbis concluded that no material other than flax—as in the fine linen of the High Priest's clothing—would allow the flame to ascend by itself. Similarly, Rami bar Hama deduced from the use of word , lehaalot, in that the Menorah flame had to ascend by itself, and not through other means (such as adjustment by the priests). Thus Rami bar Hama taught that the wicks and oil that the Sages taught one could not light on the Sabbath, one could also not light in the Temple. The Gemara challenged Rami bar Hama, however, citing a Mishnah that taught that the worn-out breeches and girdles of priests were torn and used to kindle the lights for the celebration of the Water-Drawing. The Gemara posited that perhaps that celebration was different. The Gemara countered with the teaching of Rabbah bar Masnah, who taught that worn-out priestly garments were torn and made into wicks for the Temple. And the Gemara clarified that the linen garments were meant. A Baraita taught that , “Aaron and his sons shall set it in order, to burn from evening to morning,” means that God instructed them to provide the Menorah with the requisite amount of oil so that it could burn from evening to morning. And the Sages calculated that a half-log of oil (roughly 5 ounces) would burn from evening to morning. The Gemara reported that some said that they calculated this by reducing the original quantity of oil, first filling each lamp with a large quantity of oil and on finding in the morning that there was still oil in the lamp, gradually reducing the quantity until they arrived at a half-log. Others said that they calculated it by increasing it, first filling the lamp with a small quantity of oil and the next evening increasing the quantity of oil until they arrived at the standard of the half-log.
