Why were the original Old English Bible translations created?

The Old English Bible translations are the partial translations of the Bible prepared in medieval England into the Old English language. The translations are from Latin texts, not the original languages.

Many of these translations were in fact Bible glosses, prepared to assist clerics whose grasp of Latin was imperfect and circulated in connection with the Vulgate Latin Bible that was standard in Western Christianity at the time. Old English was one of very few early medieval vernacular languages the Bible was translated into, and featured a number of incomplete Bible translations, some of which were meant to be circulated, like the Paris Psalter or Ælfric's Hexateuch.

The Old English Bible translations were created to assist clerics who didn't now much Latin.
