We must always remember that the Lord causes us the lay down in peace and gives us sweet sleep, and His angels are encamped about us to protect us. Psalm 34:7-9 KJV
The angel of the Lord encampeth round about them that fear him, and delivereth them. O taste and see that the Lord is good: blessed is the man that trusteth in him. O fear the Lord, ye his saints: for there is no want to them that fear him.
