Who is told to give the sword to the lady of the lake?

In Arthurian legend, it is the character Sir Bedivere who is instructed to return Excalibur, King Arthur's sWord, to the Lady of the Lake. After Arthur's final battle, he asks Bedivere to throw the sWord into the lake. Bedivere initially hesitates but ultimately obeys, casting the sWord into the water where it is received by the Lady of the Lake.
