Building and Destroying: Introduction

For at least the next seven or eight months, this blog will focus on hilchos Shabbos, the laws of the Sabbath.  The first of the 39 melachos, categories of prohibited work, that I will discuss are binyan (building) and sosair (destroying).  These two are very closely intertwined, because sosair is only chayav (i.e. forbidden by the Torah) when it is al m’nas livnos, for the purpose of building.  To destroy something for no reason is only prohibited d’rabanan, rabbinically.  Interestingly if someone destroys something in order to rebuild it exactly the same way, it is also patur (that is, only rabbinically prohibited) because of a concept called melacha sh’ayna tzricha gufa (which is beyond the scope of this blog).  (עיין תוס' שבת לא: ד"ה וסותר)

Binyan can be divided into a few categories.  The first is binyan b’karka (building that is attached to the ground), the av melacha (main category).  The next is binyan b’kaylim which is creating and putting together vessels.  After that is ohel, constructing a tent.  Over the next few weeks I hope to deal with each of these.  I may also discuss various rabbinic decrees surrounding binyan.
