I must admit I had to look up the Feast of Tabernacles, or Sukkot. I heard it mentioned on the radio recently and believe it is held to celebrate the gathering in of the harvest and also the Jewish exodus from Egypt. I didn't know that it was celebrated with dancing but I think I'm right in saying that people spend time in a temporary shelter called a sukkah. It sounds like a very interesting festival and your photo looks very joyful.
@busylady The Pastor tells the story as you have written. We sang Hebrew songs which was wonderful. And the gorgeous ladies danced a few times, which was delightful
