Counting the Omer represents the journey

“We are currently in the midst of one of the least understood periods of the Jewish calendar. It is called “the counting of the Omer”, the 49 days between Passover and Pentecost. It is our custom to make a special blessing on each of these days. In seasonal terms, this was the time of the grain harvests, of which an offering was brought to the Temple. But the Jewish festivals are not only about the seasons. They are also about history. From this perspective the counting of the Omer represents the journey between the Exodus (Passover) and the revelation of the Ten Commandments at Mount Sinai seven weeks later. It is, in other words, a reminder of the journey from liberation to the constitution of liberty.”
