At a traditional Jewish bar mitzvah, the blessing a boy’s father may recite to mark his changed responsibility is Baruch shep'tarani.
The phrase comes from a longer blessing commonly transliterated as “Baruch shep'tarani me-onsho shel zeh,” meaning that the father is blessed because he is no longer liable for the son’s punishment. It reflects the traditional idea that the boy now bears personal religious responsibility for his commandments.
The practice is associated particularly with Orthodox and traditional communities, but it is not universal. Some families omit it, while others recite it without the usual blessing formula. It should not be confused with Shehecheyanu, a blessing of gratitude for reaching a significant occasion, or Birkat Hamazon, the grace after meals.
