Shavuot, which begins on the evening of May 23, is also known as Chag HaBikkurim, which celebrates the season’s harvest of its first and best fruits. In ancient times, farmers would tie reeds around the first ripening fruits and grains in their fields. The designated produce, called bikkurim, was harvested upon ripening. Following harvest, the farmers made a pilgrimage to the Temple in Jerusalem for Shavuot where each farmer presented his bikkurim to a priest. During the presentation ceremony the farmer thanked G-d for his sustenance provided by nature.
