Hymn Lyrics Search - Name That Hymn

Here are the lyrics:
The inn was full
No room for Mary in the public place
they turned away more troubled grew the look on Mary's face
then to the darkened cattle stall their tired feet found a way
then lo the humbled spot grew bright as if it at break of day
lo watchers murmur lo
for the sleeping child
herald angels lullaby
and Mary's voice so mild
small and still the hallowed Christ
head where the thorns belong
earth and stars and heavens sing a gentle cradle song.
