This is a small parchment roll with forty-nine oval medallions, each with a painted frame of flowers. Inside each medallion is the number of the days and weeks of the Omer. After the holiday of Passover, seven times seven, that is, forty-nine days have to be counted until the next holiday, the ‘Holiday of Weeks’, or Pentecost, called Shavuot in Hebrew. These are the days of the Omer. The counting of the days is a Biblical commandment. It dates to the times of the Temple in Jerusalem, when the harvest and sheaving of barley started on the second day of Passover, and on every day a sacrifice containing an omer-measure of barley was offered in the Temple. This ancient feast of wheat harvest gained a spiritual content in the Biblical narrative: according to tradition, Moses received the Torah – that is, the Oral and the Written Law – on Mount Sinai on this day. The period of the counting of the Omer thus connects Passover, which is the holiday of physical freedom from slavery and of becoming a free nation with the holiday of becoming a spiritual community. The counting of the Omer ends with Shavuot, the holiday of the Giving of the Torah, when the Jewish people received the Law and became obliged to remember common past, slavery in Egypt and the exodus.
