In a Jewish bar or bat mitzvah service, the reading from the Prophets that follows the Torah reading is called the haftarah.
The haftarah is a selected passage from the books of the Hebrew Bible known as the Prophets, or Nevi’im. It is traditionally connected thematically or historically with the weekly Torah portion or with the Jewish calendar. The reading normally follows the public reading from the Torah on Shabbat and certain festivals.
A bar or bat mitzvah celebrant may chant the haftarah and its associated blessings, although local customs vary. The haftarah is not the same thing as the Torah portion: the Torah portion comes from the Five Books of Moses, while the haftarah comes from later prophetic books. The term is often explained as “conclusion” or “completion,” though its precise historical development is discussed by scholars. Pronunciation and musical traditions differ across Jewish communities.
