My Angel ever at my side
how lovely you must be -
To leave your home in heaven,
to guard someone like me.
When I'm far away from home,
or maybe hard at work
I know you will protect me,
from harm along the way.
Your beautiful and shining face,
I see not, though you're near
the sweetness of your lovely voice,
I cannot really hear.
When I pray, you're praying too,
your prayer is just for me.
But, when I sleep you never do,
you're watching over me.
