Lully, lullay (with what child is this?)

What child is this who laid to rest
On Mary's lap is sleeping
Whom angels greet with anthem sweet
While shepherds watch their 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
The babe, the son of Mary

Lullay though little tiny child
Bye, bye lully lullay
