The arrival at the end of the book of Deuteronomy and the return to the start of Genesis is a time for celebration and is renowned as one of the most joyful days in the Jewish calendar.
The whole event is symbolic of a marriage between the Jewish people and the Torah. Two people are called to say the blessings before and after the reading of the Torah. The one who performs this mitzvah before the Deuteronomy reading is called the ‘Chatan Torah’ (bridegroom of the Torah); the other ‘Chatan B’reishit’ (bridegroom of Genesis). This is a special honour.
