Maimonides taught that Shavuot (mentioned in ) is the anniversary of the Revelation on Mount Sinai. To increase the importance of this day, Jews count the days that pass from the preceding festival of Passover, just as one who expects an intimate friend to visit on a certain day counts the days and even the hours until the friend comes. This is why Jews count the days that pass since the offering of the Omer, between the anniversary of the Israelites' departure from Egypt and the anniversary of the Lawgiving. The Revelation at Mount Sinai was the object of the Exodus from Egypt, and thus God said in "I brought you to myself." As the Revelation at Mount Sinai took place on one day, so Jews keep its anniversary only one day.
