Weekly Message from the Board President

So here’s a question.  Why do they call it a fast, when the day seems to go by very slowly when you’re fasting.  It’s something to ponder on Yom Kippur, though the Rabbi may have a different idea on what you should be thinking about.

Kol Nidre is tomorrow night (Tuesday, October 4).  The services start at the Synagogue at 6:30 PM.  They will also be on Zoom.  The Zoom call starts at 6.  https://us02web.zoom.us/j/84206415654.  Meeting ID: 842 0641 5654.

Wednesday morning, services start at 9:30 AM.  They will also be on Zoom, and the Zoom call will begin 30 minutes earlier, at 9.  https://us02web.zoom.us/j/81275837658 Meeting ID: 812 7583 7658. 

Rabbi Halfon says the Yom Kippur day services will run till about 1.  Then there will be a break, and services will resume at 5:30 PM.  Again, the Zoom call will start 30 minutes earlier, at 5 PM.  The Zoom meeting will begin at 5.  https://us02web.zoom.us/j/81997128666 Meeting ID: 819 9712 8666. 

Break the Fast will immediately follow.  It may be because we’re hungry, but it always seems like the food served at the Break the Fast is really, really good.  Our thanks to Sisterhood for magically making the food appear as we wind up services.

Rabbi Halfon has been working very hard preparing for the High Holy Day services. You saw the first part of his efforts during Rosh Hashanah.  He’s putting in an equal effort for Yom Kippur.  The Rabbi says his sermon will look ahead to the future, and what Mt. Sinai might look like in the year 2030.  We’re excited to see his dream and what it will include.  (Will it include Rabbi Halfon wearing a cowboy hat during Cheyenne Frontier Days?  That one might be a stretch…)

Yom Kippur is not the end of the holidays.  Sukkot is coming up this weekend.  We’ll have services in the Sukkah in the back yard of the Synagogue weather permitting, on Sunday night.  If the weather is bad, we’ll move things indoors.  The services will start at 6 PM Sunday.  The Zoom call starts at 5:30 PM. https://us02web.zoom.us/j/86705843186  Meeting ID: 867 0584 3186.

This is Rabbi Halfon’s second set of High Holy Day services with Mt. Sinai.  He started working for the Synagogue in August of last year.  The Rabbi has been our biggest cheerleader.  He eagerly welcomes people to who reach out to the Synagogue via email, phone calls, or in person.  He’s joined the Cheyenne Interfaith Council and was just elected to the Board of the Wyoming Interfaith Network.  He’s met local members of the clergy, and traveled to Laramie and Ft. Collins to meet with the Jewish communities there.  The Rabbi is filled with excitement and enthusiasm about Mt. Sinai, and always has lots of ideas for ways to make the Synagogue grow and do more.

The Endowment Board would like to thank the Rabbi for his efforts, and is excited about what he is offering our community.  The Endowment Fund is raising money in October for a chair in the large sanctuary, with a plaque honoring Rabbi Halfon.

Money raised will stay in the Endowment Fund, but a portion of the interest will be given to the Synagogue to help with our expenses.  The chairs are $500, but an anonymous donor has offered to cover half the cost under certain conditions.  If you would like to donate, please use our website or contact the Synagogue office.

Here’s our Yiddish Phrase of the Week:

Shtek nit dem kop tsum volf in moyl arayn.
Don’t stick your head in a wolf’s mouth.
