וּבְי֣וֹם הַבִּכּוּרִ֗ים בְּהַקְרִ֨יבְכֶ֜ם מִנְחָ֤ה חֲדָשָׁה֙ לַֽיהוָ֔ה בְּשָׁבֻעֹ֖תֵיכֶ֑ם מִֽקְרָא־קֹ֙דֶשׁ֙ יִהְיֶ֣ה לָכֶ֔ם כָּל־מְלֶ֥אכֶת עֲבֹדָ֖ה לֹ֥א תַעֲשֽׂוּ׃
칠칠절 처음 익은 열매 드리는 날에 너희가 여호와께 새 소제를 드릴 때에도 성회로 모일 것이요 아무 노동도 하지 말 것이며
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.”
