The Babylonian armies of King Nebuchadnezzar breached the walls of Jerusalem on the 9th of Tammuz in the year 3338 from creation (423 BCE); King Ziddikiahu of Judah was captured and taken to Babylon (Jeremiah 39:5. A month later, the capture of Jerusalem was completed with the destruction of the Holy Temple and the exile of all but a small number of Jews to Babylon). Tammuz 9 was observed as a fast day until the second breaching of Jerusalem's walls (by the Romans) on the 17th of Tammuz, 3829 (69 CE), at which time the fast was moved to that date. (Talmud, Rosh Hashanah and Tur Orach Chaim 549)

What is a mitzvah?
An act of uniting heaven and earth.
But heaven is spiritual and earth is material. To make spirit and matter one is impossible!
A creature of earth cannot make earth heaven. And a heavenly being cannot bring heaven to earth.
But for you, it is not impossible.
This mitzvah that I am commanding you today is not impossible for you. It’s not even distant. It’s very close to you, in your mouth and in your heart to do it. (Deut. 30:11)
It is close to you because the Torah was given to you both written and orally. (Rashi)
Because within you breathes the Creator of both heaven and earth.
So that when you speak the words of His written Torah, you bring heaven down to earth.
And when you explain the words of His oral Torah, you bring earth up to heaven.
Indeed, you accomplish the impossible every day.
