In a Jewish bar or bat mitzvah ceremony, the blessing recited after the Torah reading is called Birkat HaTorah.
Birkat HaTorah means “the blessing of the Torah.” Torah readers traditionally recite one set of blessings before reading and another after finishing their assigned passage. These blessings express gratitude for the Torah and praise God as the giver of Torah. The exact wording and musical chanting vary among Jewish traditions.
The post-reading blessing is part of the formal Torah-reading procedure, so it is separate from a celebrant’s personal speech or from a general congregational prayer. It should also be distinguished from Birkat Hamazon, the grace after a meal, and Shehecheyanu, a blessing associated with reaching special occasions or new experiences. At a bar or bat mitzvah, the celebrant may perform some or all of the reading-related roles according to the synagogue’s customs and the student’s preparation.
