וּבְי֣וֹם הַבִּכּוּרִ֗ים בְּהַקְרִ֨יבְכֶ֜ם מִנְחָ֤ה חֲדָשָׁה֙ לַֽיהוָ֔ה בְּשָׁבֻעֹ֖תֵיכֶ֑ם מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֥א תַעֲשֽׂוּ׃
Pada hari buah sulung, ketika kamu mempersembahkan kurban sajian baru kepada Yang Mahakekal pada hari raya Tujuh Minggumu, haruslah ada pertemuan kudus bagimu; janganlah kamu melakukan pekerjaan apa pun yang berupa kerja.
Mishnah Sanhedrin
[Cases concerning offenses punishable by] beating [are decided] by three. In the name of Rabbi Yishmael they said twenty-three. The intercalation of the month and intercalation of the year [are decided] by three, according to Rabbi Meir. Rabban Shimon ben Gamaliel says: “The matter is begun by three, discussed by five, and decided upon by seven. But if they decided upon it with three, the intercalation is valid.”
