Come, peasant, king, to own Him;

"What Child Is This?"
Written by William Chatterton Dix in 1865 at age 29
Tune: "Greensleeves"

1. What Child is this who, laid 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 laud,
The Babe, the Son of Mary.

2. Why lies He in such mean estate,
Where ox and ass are feeding?
Good Christians, fear, for sinners here
The silent Word is pleading.

Nails, spear shall pierce Him through,
The cross be borne for me, for you.
Hail, hail the Word made flesh,
The Babe, the Son of Mary.

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

Raise, raise a song on high,
The virgin sings her lullaby.
Joy, joy for Christ is born,
The Babe, the Son of Mary.

What child is this, who lays to rest,
On marys 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,
The babe, the son of mary.

This, this is christ the king
Whom shepherds guard and angels sing.
Haste, oh haste to bring him praise,
The babe, the son of mary.
The babe, the son of mary.
