The Omer is a sacrifice of fresh fruits as specified in Leviticus 2:9-11. The cup itself is the golden vessel that contained the Omer and was used on the second day of Passover when a measure of barley, a tenth of an epah, equal to one and a half pints of fine flour, was offered to the Temple as the fresh fruits of the field. The waving of the cup in different directions during the offering corresponded to the waving of the lulav. The addition of the pomegranate for the reverse design served as a symbol with a variety of interpretations. One belief was that by eating it your merits would will increase by the number of seeds in the fruit. Another belief was that there were 613 seeds in the fruit, thus equating it with the number of commandments in the Torah.
