Psalm 121: The Keeper Who Never Sleeps
Psalm 121 answers the traveler's anxiety with a person rather than a technique: help comes from Yahweh, who made heaven and earth and never sleeps. It promises the Keeper's presence and the keeping of your soul, not a hazard-free trip.
Psalm 121:3–4: Does God Sleep?
The pilgrim looks to the hills and asks where help comes from. Psalm 121 answers that the keeper of Israel does not doze off, so the one who trusts him is not left unguarded.
