Today is the first day of the seven day holiday of Sukkot. It marks the end of the biblical holidays of the year. It is also the last of the three festival holidays that required Jews to go to Jerusalem to offer their offerings and worship G-d. Sukkot is mentioned in John 7. There it describes Yeshua going up to Jerusalem and teaching. The biblical cycle of holidays begins with Passover, followed by Shavuot and ending with sukkot.
