For He Gives...

Proverbs 3:24 English Standard Version (ESV)

24 If you lie down, you will not be afraid;

    when you lie down, your sleep will be sweet.

Psalm 4:8 English Standard Version (ESV)

8 In peace I will both lie down and sleep;

    for you alone, O Lord, make me dwell in safety.

Psalm 127:2 English Standard Version (ESV)

2 It is in vain that you rise up early

    and go late to rest,

eating the bread of anxious toil;

    for he gives to his beloved sleep.

...to his beloved sleep.  Go to bed with enthusiasm and great joy, for it is a gift of God's grace.
