The Book of Tobit is an apocryphal story of two families living in Assyrian exile during the 8th century BCE, likely composed between the 3rd and 2nd centuries BCE in Hebrew or Aramaic. It tells of a righteous man named Tobit (Tobi), his son Tobiyah, and a woman named Sarah, whom Tobiyah ultimately marries, focusing on the characters’ prayer, good deeds, and the miraculous divine intervention they experience. Traces of the work's influence are evident in later texts: Midrash Bereishit Rabbah includes a truncated Aramaic version of Tobit, and one medieval manuscript suggests that at least in some medieval communities, the work was publicly read on the holiday of Shavuot.
