Born in Thessaloniki, he was the son of Joseph the Philosopher and brother of Jochebed, Shabbatai Zevi's last wife. Jochebed (also called ‘Ā’ishah following her conversion to Islam) claimed that he was the reincarnation of her late spouse, so that he might succeed to the leadership of Sabbatai's followers.[1] He attracted a considerable following of his own, called Ya‘qōviyīm or Yakubiler.[1]
