Targum, (Aramaic: "Translation," or "Interpretation"), any of several translations of the Hebrew Bible or portions of it into the Aramaic language. The word originally indicated a translation of the Old Testament in any language but later came to refer specifically to an Aramaic translation.
The status and influence of the Targums became assured after the Second Temple was destroyed in AD 70 when synagogues replaced the Temple as houses of worship. For it was in the synagogue that the practice of reading from the Old Testament became widely observed, along with the custom of providing these readings with a translation into Aramaic.
When Scripture was read aloud in the synagogue, it was translated aloud by a meturgeman, or professional interpreter (hence the name Targum), for the benefit of the congregation. The translator tried to reproduce the original text as closely as possible, but since his object was to give an intelligible rendering of the biblical text, the Targums eventually took on the character of paraphrase and commentary, leaving literal translation behind. To prevent misconceptions, a meturgeman expanded and explained what was obscure, adjusted the incidents of the past to the ideas of later times, emphasized the moral lessons to be learned from the biblical narratives, and adapted the rules and regulations of the Scriptures to the conditions and requirements of the current age.
