It is a double celebration today, with Jewish Shavuot and Christian Pentecost coming on the same day.
Today Jews celebrate Shavuot, also know by its Biblical names Chag HaKatsir, the [wheat] Harvest Festival, and Yom HaBikurim, Day of the First Fruits.
By tradition today also marks the day of King David's birth and death.
But mainly Shavuot is Zman Matan Toratenu, The Season of the Giving of our Torah.
Seven weeks (shavuot = weeks) have passed since Passover.
It took 49 (+1) days of wandering in the desert for God and Moses to prepare the People for the the biggest day in history.
In today's morning prayer service Exodus 19-20 is read.
All rise in silent reverence to listen to the Ten Commandments with the feeling that we all are standing at Mount Sinai.
scroll of the Book of Ruth is also chanted, in loving memory of David
and of Ruth, his Moabite ancestor, the mother of all converts.
In the dim recesses of the Church of the Holy Sepulchre, a priest and his reflection.
What almost looks like a flame above his head reminds us that this Sunday is Pentecost for some Christians.
Book of Acts says that the Apostles were gathered together in one place
[in Jerusalem's Upper Room] when suddenly a sound came from heaven like a rushing
wind, filling the entire house where they were sitting.
Then tongues of fire appeared and one sat upon each one of Apostles!
They were all filled with the Holy Spirit and began to speak in other languages as directed by the Holy Spirit.
Chag sameach, happy holiday to you, whichever festival you are celebrating today!
