How would they perform the rite of the harvest of the omer? Emissaries of the court would emerge on the eve of the festival of Passover and fashion the stalks of barley into sheaves while the stalks were still attached to the ground, so that it would be convenient to reap them. The residents of all the towns adjacent to the site of the harvest would assemble there, so that it would be harvested with great fanfare. Once it grew dark, the court emissary says to those assembled: Did the sun set? The assembly says in response: Yes. The emissary repeats: Did the sun set? They again say: Yes. The court emissary next says to those assembled: Shall I reap the sheaves with this sickle? The assembly says in response: Yes. The emissary repeats: With this sickle? The assembly says: Yes. The court emissary then says to those assembled: Shall I place the gathered sheaves in this basket? The assembly says in response: Yes. The emissary repeats: In this basket? The assembly says: Yes. If the sixteenth of Nisan occurs on Shabbat, the court emissary says to the assembled: Shall I cut the sheaves on this Shabbat? The assembly says in response: Yes. The emissary repeats: On this Shabbat? The assembly says: Yes. The court emissary says to those assembled: Shall I cut the sheaves? And they say to him in response: Cut. The emissary repeats: Shall I cut the sheaves? And they say to him: Cut. The emissary asks three times with regard to each and every matter, and the assembly says to him: Yes, yes, yes. The mishna asks: Why do I need those involved to publicize each stage of the rite to that extent? The mishna answers: It is due to the Boethusians, as they deny the validity of the Oral Law and would say: There is no harvest of the omer at the conclusion of the first Festival day of Passover unless it occurs at the conclusion of Shabbat. The publicity was to underscore that the sixteenth of Nisan was the proper time for the omer harvest.

MISHNA: After the witnesses have been examined and their testimony accepted, the head of the court says: It is sanctified. And all the people respond after him: It is sanctified; it is sanctified. Whether the moon was seen at its anticipated time, on the thirtieth day of the previous month, or whether it was not seen at its anticipated time, in which case witnesses are not necessary to establish the following day as the New Moon, the court sanctifies it and formally proclaims the day as the New Moon.
