Yoma, Chapter 3, Mishnah 7. This mishnah deals with the details of the linen garments worn by the Kohen Gadol, garments designated specifically for the service of Yom Kippur. The mishnah distinguishes between two sets of linen garments that he wore over the course of the day: one set for the morning service - the Yom Kippur offerings that we will yet learn about; and a second set in the afternoon, when he entered the Holy of Holies again to remove the spoon and the fire pan that had been left there for the incense. For that entry he would put on an additional set of white garments.
The words of Rabbi Meir:
"Bashachar hayah loveish Pelusin" - Pelusin is a fine type of Egyptian linen that comes from the region called Pelusin, which is the region known as Ra'amses. These garments were worth twelve maneh, that is, twelve hundred dinar.
"Uvein ha'arbayim" - the linen garments he wore in the afternoon were Hinduyin, from India, "shel shemoneh me'os" - worth eight hundred dinar.
"Vachachamim omrim":
The Sages gave a higher price:
"Bashachar hayah loveish shel shemoneh esreh maneh" - the garments he wore in the morning were worth eighteen hundred dinar.
"Uvein ha'arbayim hayu shel sheneim asar maneh" - worth twelve hundred dinar, which is the sum that according to Rabbi Meir he wore in the morning.
"Hakol sheloshim maneh":
The mishnah notes that in total - the morning garments worth eighteen hundred dinar and the afternoon garments worth twelve hundred dinar - they all came to thirty maneh, three thousand dinar. The Gemara explains that the mishnah added up the figures for us and wrote "hakol sheloshim maneh" in order to teach us that the Kohen Gadol is not obligated to keep to the exact sums that were listed. As long as the morning garments are more expensive than the afternoon garments, and the total stands at thirty maneh, he may change the division: there is no requirement that it specifically be eighteen maneh in the morning, but rather he may make it sixteen maneh in the morning and fourteen maneh in the afternoon.
"Eilu mishel tzibur":
The mishnah concludes that these sums are what the community provided from public funds. However, "im ratzah lehosif, mosif mishelo": if the Kohen Gadol wished to make the garments more expensive, he is permitted to add, but the addition must come from his own private funds.
In summary: in this mishnah we learned about the two sets of linen garments of Yom Kippur - those of the morning and those of the afternoon; about the dispute between Rabbi Meir and the Sages regarding their value; about the meaning of the total "hakol sheloshim maneh," which teaches that the precise division is not insisted upon, only the total and the fact that the morning garments must be of greater value; and about the fact that the garments come from public funds, while any addition beyond that comes from the Kohen Gadol himself.
