Today’s mishnah describes implements used to measure Temple offerings, and much like measuring cups today, these tools came in standard fractional sizes. There was a quarter-log vessel (about a scant half cup), which measured the precise amount of water needed to purify people with the skin disease tzaraat or the quantity of oil added to a nazirite’s bread offering. The half-log vessel scooped water for the trial of the suspected adulteress (sotah) and measured oil for the unleavened breads presented alongside the thanksgiving offering. A vessel that held a full log measured oil for most other meal offerings. As will soon become clearer, it seems that the purpose of these anointed vessels was not just to measure, but also to consecrate the contents.
In the Gemara on today’s daf, Rabbi Yehuda HaNasi asks whether it was truly necessary to have all of these different-sized implements, starting with a quarter-log vessel:
For what purpose was the quarter-log measuring vessel anointed with the anointing oil? If you suggest it was necessary in order to measure the water used in the purification of a person with tzaraat, one can counter that the rite is performed outside the Temple, and so it does not require a service vessel. And if you suggest it was for measuring the oil for the loaves of a nazirite, one can counter that the loaves of a nazirite are consecrated through the slaughter of the ram he brings.
The mishnah names two uses for the quarter-log vessel: measuring water for the purification of a person with tzaraat and measuring oil to prepare a nazirite’s loaves. The first, Rabbi Yehuda HaNasi points out, could be done outside the Temple in an ordinary, unconsecrated vessel. The second also can be measured in an ordinary vessel, since the loaves become sacred when the ram they accompany is slaughtered. So what purpose does the smallest measuring cup serve?

Rabbi Hiyya explains:
The consecration of the quarter-log measuring vessel was necessary, as with it one would measure oil for the high priest’s griddle-cake offering, as a quarter-log of oil is used for each and every loaf.
In praise for resolving his difficulty, Rabbi Yehuda HaNasi read the verse about Rabbi Hiyya, who had traveled from Babylonia to join Rabbi Yehuda HaNasi in the land of Israel: “The man of my counsel from a far country” (Isaiah 46:11).
Rabbi Hiyya points to another use of the quarter-log vessel for which it needs to be consecrated: measuring oil to be included in the high priest’s griddle cakes. Because this was undertaken within the boundaries of the Temple, it needed to be consecrated. Because of Rabbi Hiyya’s insight, Rabbi Yehuda offers him praise, highlighting his travels from Babylonia to the land of Israel.
Now, Rabbi Yehuda HaNasi offers a similar question about the half-log vessel:
For what purpose was the half-log measuring vessel anointed with the anointing oil? If you suggest it was necessary in order to measure the water used in the rite of the sotah, one can counter: Is the water that was used non-sacred such that it is necessary to consecrate it? Isn’t it written: “And the priest shall take holy water in an earthen vessel” (Numbers 5:17)? And if you suggest that it was for measuring the oil for the loaves of a thanksgiving offering, one can counter that the loaves of a thanksgiving offering are consecrated through the slaughter of the thanksgiving offering.
While the sotah ritual required a half-log of consecrated water, the Torah states it was scooped from a vessel containing water that was already consecrated; a special vessel was not necessary to consecrate it. Similarly, the thanksgiving offering loaves were consecrated when the animal was slaughtered, so the vessel was not needed to sanctify the oil for the loaves.
This time, Rabbi Yehuda HaNasi’s son Rabbi Shimon offers the answer:
The consecration of the half-log measuring vessel was necessary, as with it one would distribute a half-log of oil to each and every lamp of the menorah.
Rabbi Yehuda HaNasi said to his son in praise: Lamp of Israel! Indeed, that was its use.
Like Rabbi Hiyya, Rabbi Shimon points to a ceremonial use in the Temple for which a consecrated half-log implement was necessary: measuring and sanctifying the oil poured into each lamp of the menorah. And again, Rabbi Yehuda offers praise, this time playing off his son’s comments and emphasizing his brightness.
It turns out that the Temple did, indeed, require the full set of sanctifying measuring cups.
See you tomorrow!
