Proverbs 3:24-26
24 When you lie down, you will not be afraid;
Yes, you will lie down and your sleep will be sweet.
25 Do not be afraid of sudden terror,
Nor of trouble from the wicked when it comes;
26 For the LORD will be your confidence,
And will keep your foot from being caught.
Very comforting, esp when you are all alone in the night. God is always with you.
