In the first decades of the 5th century, Rav Ashi (d. 427) and Ravina I (d. 421) led a group of the Amoraim (Talmudic sages) in the massive undertaking of compiling the Babylonian Talmud -- collecting and editing the discussions, debates and rulings of hundreds of scholars and sages which had taken place in the more than 200 years since the compilation of the Mishnah by Rabbi Judah HaNassi in 189. The last of these editors and compilers was Ravina II, who passed away on the 13th of Kislev of the year 4235 from creation (475 CE); after Ravina II, no further additions were make to the Talmud, with the exception of the minimal editing undertaken by the Rabbanan Savura'i (476-560). This date thus marks the point at which the Talmud was "closed" and became the basis for all further exegesis of Torah law.

What Is the Talmud?
When you build a new house, you must make a fence for your roof. (Deut. 22:8)
The Torah speaks quite literally about a new house. But it’s also providing a paradigm for all forms of growth.
Because bigger houses come with bigger challenges. The more you engage the outside world, the more you need to protect yourself from falling.
How do you protect yourself? With a fence on your roof.
Meaning: With something that is beyond yourself.
Simply put, the higher you rise, the tighter you need to connect to the One who will always be just as far above you.
That way, you will not fall, and neither will those who enter your house.
