what child is this lyrics

What child is this who lays to rest?
On Mary's lap is sleeping
Whom angels greet with anthems sweet
While shepherds watch are keeping

This, this is Christ, the King
Whom shepherds guard and angels sing
Haste, haste to bring Him praise
The Babe, the Son of Mary

So bring Him incense, gold and myrrh
Come peasant, king to own Him
The King of Kings, salvation brings
Let loving hearts enthrone Him

This, this is Christ, the King
Whom shepherds guard and angels sing
Haste, haste to bring Him praise
A Babe, the Son of Mary
