Tractate Sukkah discusses the various observances of the joyous holiday of Sukkot: dwelling in a Sukkah, taking of the Four Kinds, and the festive dancing and praying that characterizes the weeklong celebration.

The tractate concludes with the story of Miriam of the Bilga clan, who had married a Greek and then acted disrespectfully in the Temple, and how the Sages dealt with her clan.
