A targum was an originally spoken translation of the Hebrew Bible that a professional translator would give in the common language of the listeners when that was not Biblical Hebrew. This had become necessary near the end of the first century BC, as the common language was Aramaic and Hebrew was used for little more than schooling and worship. The translator frequently expanded his translation with paraphrases, explanations and examples, so it became a kind of sermon.

The Hebrew Bible or Tanakh, also known in Hebrew as Miqra, is the canonical collection of Hebrew scriptures, comprising the Torah, the Nevi'im, and the Ketuvim. Different branches of Judaism and Samaritanism have maintained different versions of the canon, including the 3rd-century BCE Septuagint text used in Second Temple Judaism, the Syriac Peshitta, the Samaritan Pentateuch, the Dead Sea Scrolls, and most recently the 10th-century medieval Masoretic Text compiled by the Masoretes, currently used in Rabbinic Judaism. The terms "Hebrew Bible" or "Hebrew Canon" are frequently confused with the Masoretic Text; however, this is a medieval version and one of several texts considered authoritative by different types of Judaism throughout history. The current edition of the Masoretic Text is mostly in Biblical Hebrew, with a few passages in Biblical Aramaic.
