Many Jews follow the custom called "Selihot" which consists of getting up every night to go to the synagogue from the first day of "Elul". They begin to pray and seek forgiveness until dawn, then they go to their work. The intensity of this custom increases during the ten days between Yom Kippur and Rosh Hashanah. This is called "Yamim Nora'im" which means "Redoubtable Days". The Jews greet each other in these days with the following prayer: "May you be inscribed in the Book of Life" while asking God for forgiveness.
Judaism is the oldest of the Abrahamic religions, and one of the oldest monotheistic religions in the world, it is 3000 years old. Judaism is associated with the Jewish people, since the religion is not a missionary faith, meaning that it is not open to people of non-Jewish origins. Today, the Jewish population is approximately 14.5-17.4 million.
