The promise is expanded from one person to all of God's people. Unlike a human guard who tires, God's watchful care is utterly unceasing — a foundational promise of Scripture.
Memory phrase: God never slumbers or sleeps.
Talk about it: What happens when a guard falls asleep on the job? Why is it so good that God never does?
Prayer: God, what a comfort it is that You never stop watching over Your people. Thank You for watching over me all night long.
