Jane Siberry what child is this

What child is this who's laid to rest
On Mary's lap is sleeping?
Whom angels greet with anthems sweet
While shepherd's watch are keeping
This, this is Christ the King
Whom shepherds guard and angels sing
Haste, haste to bring him, Lord
The babe, the son of Mary
So bring him incense, gold and myrrh
Come peasant, king to all of him
The king of kings, celebration brings
That loving hearts enthrone him
Raise, raise the song on high
The virgin sings her lullaby
Joy, joy for Christ is born
The babe, the son of Mary
