Two more takanos of Rabban Yochanan ben Zakkai
keeping the Mikdash alive without it
The lulav — and the Omer
Chadash: new grain, forbidden until the Omer
The lulav: seven days — where?
While the Beis HaMikdash stoodIn the Mikdash, seven days — in the medinah, only one→ seven in the Mikdash, one elsewhere
“Rejoice before Hashem seven days”Vayikra 23:40
After the Churban — Rabban Yochanan ben ZakkaiEverywhere, seven days→ seven everywhere — in memory of the Mikdash
The whole day of the Omer — forbidden
Rabban Yochanan ben ZakkaiThe entire day is forbidden for the new grain→ eat the new grain only from the next day
Rabbi Yehuda (Menachos): it is Torah law
Lest, once the Mikdash is rebuilt, they eat before the korban
Or: to permit chadash at all, with no korban
Rosh Hashana 4:3
The Takanos for the Lulav and Yom HaNef
תַּקָּנוֹת הַלּוּלָב וְיוֹם הָנֵף
בָּרִאשׁוֹנָה הָיָה הַלּוּלָב נִטָּל בַּמִּקְדָּשׁ שִׁבְעָה,
וּבַמְּדִינָה יוֹם אֶחָד.
מִשֶּׁחָרַב בֵּית הַמִּקְדָּשׁ,
הִתְקִין רַבָּן יוֹחָנָן בֶּן זַכַּאי
שֶׁיְהֵא לוּלָב נִטָּל בַּמְּדִינָה שִׁבְעָה זֵכֶר לַמִּקְדָּשׁ,
וְשֶׁיְּהֵא יוֹם הָנֵף כֻּלּוֹ אָסוּר.
