Every night during Chol Hamoed Succot, there're singing and dancing everywhere. This holy custom dates back to the Holy Temple, when Simchat bet Hashoeva, the "Drawing of the Water" celebration would take place nightly during Sukkot. The Sages noted that "Whoever never witnessed the Simchat Beit Hashoeva has never in his life seen true joy." They have left us wonderful descriptions of the scenes that inspire us with longing to witness it once again.
Here's what Simchat Bet Hashoeva looks like today in Israel, in the court of the Lelover Chassidim in Bet Shemesh. Enjoy, and have a wonderful Shabbat and Chol Hamoed!
