Now I lay me down to sleep is a classic children's bedtime prayer from the 18th century.
Perhaps the earliest version was written by Joseph Addison in an essay appearing in The Spectator on March 8, 1711. It says:
When I lay me down to Sleep,
I recommend my self to His care;
when I awake, I give my self up to His Direction,
Amen.
A later version printed in The New England Primer goes:
Now I lay me down to sleep,
I pray the Lord my soul to keep,
If I should die before I wake,
I pray the Lord my soul to take.
Now I lay me down to sleep,
I pray the Lord my soul to keep,
His Love to guard me through the night,
And wake me in the morning's light.
Now I lay me down to sleep,
I pray the Lord my soul to keep.
May the angels watch me through the night,
and keep me in their blessed sight.
Amen
Lord I lay me down to sleep,
I pray the Lord my soul to keep,
thy angels watch me through the night,
And keep me safe till morning's light.
Now I lay me down to sleep,
I pray the Lord my soul to keep.
Angels watch me through the night,
And wake me with the morning light.
Amen
Now I lay me down to sleep,
I pray the Lord my soul to keep.
Guide me through the starry night,
Wake me when the sun shines bright.
Amen
Now I lay me down to sleep,
I pray the Lord my soul to keep.
Guide me safely through the night,
Wake me with the morning light.
Amen
Now I lay me down to sleep.
I pray the Lord my soul to keep.
When in the morning light I wake,
Show me the path of love to take.
Amen
(Additional third verse)
If I should live another day
I pray the Lord to guide my way.
Amen
Now I lay me down to sleep.
I pray the Lord my soul to keep.
For if I die before I wake,
that's one less test I have to take.
It is sometimes combined with the "Black Paternoster", one version of which goes:
Matthew, Mark, Luke and John,
Bless the bed that I lie on.
Four corners to my bed,
Four angels round my head;
One to watch and one to pray
And two to bear my soul away.
