The lyrics of this Christmas Carol tell that part of the Nativity Story where an angel appears to a group of shepherds and tells them to go and find the baby Jesus in a manger. The melody is called "Winchester" or "Winchester Old" and was originally arranged by William Henry Monk (1823-1889) who also wrote the well-known hymn tune Abide With Me.
