- Ezra HaSofer died
- The Torah was translated to Greek
- The siege on Yerushalayim (that lead to the destruction of the Beit HaMikdash) began
When the Torah was translated to Greek it was a very dark day for us because it was the exact opposite of what Ezra HaSofer had done. It was a formulation of the letters of the Torah such that all the darkest and lowest elements could also receive blessing from the letters and words of Torah. This gave them the ability to bring the darkness of their shallow and physicality-absorbed culture to the masses and to muddle the light of the true Torah of Bnei Yisrael. It also tainted Bnei Yisrael and tempted and involved and confused them with the darkness of the Greek culture.
Lastly, when the Beit HaMikdash was destroyed, it was a further hiding and cutting off of the blessings of Shamayim.
