Introduction to Laws of Shabbat from Yeshivat Har Etzion in Israel

[Jewscout]

so i have just got a subscription to lessons from my Rabbi's Yeshiva. They have a virtual Beit Midrash and i thought it would good to share some of the lessons that i've recieved. I will warn you some of this stuff is a bit advanced so if you have any questions regarding things on there feel free to ask. The lesson is far too long so i will paste the opening and then the link to the full lesson for those who want to read. It is very informative and an excellent source on traditionaly judaism.

Shiur #01: Introduction to the Laws of Shabbat
By Rav Baruch Gigi
Translated by David Silverberg

Preface

Although the Torah makes frequent mention of the
obligation of Shabbat observance, its importance and the
severity of its violation[1], the Mishna in Masekhet Chagiga
(10a) declares, "The laws of Shabbat are like mountains
suspended by a hair." These halakhot, with which we will
deal in this series, entail fundamental principles described
by the Mishna as "mountains," all of which are "suspended by
a hair," as the written Torah offers very little information
concerning the halakhic details of Shabbat. It only alludes
to them in various places, such that they can be determined
only through Chazal's derashot (extrapolations from the
text).

We will open this series with a preliminary overview of
the different areas included under the general category of
Shabbat. Needless to say, we will not, at this stage,
address the halakhic details. The purpose of this overview
is to acquaint ourselves with the range of topics associated
with Shabbat, and develop the conceptual concepts that lie
at the heart of Hilkhot Shabbat.
