Esau is the name of a young donkey that happens to live in the stable where Jesus is born. He becomes witness to all that happens following the birth of Jesus, including the angels appearing before the shepherds, the shepherds' visit to the manger, and the visitation of the three wise men. During all this, he finds a special place for himself and his relationship with the new baby, and he takes it upon himself to be the guardian over the events of the nativity.
