Psalm 121:8

Psalm 121 belongs to a set called the Songs of Ascents, sung by pilgrims as they physically climbed the roads toward Jerusalem for the festivals, roads that ran through exposed hill country where heat, wild animals, and bandits were real hazards rather than figures of speech. For people walking that route, a promise of being kept was a practical comfort tied to the actual danger under their feet.

“Going out and coming in” was a common Hebrew way of naming the whole of ordinary life: every departure and every return, the small errand as much as the long trip. Ending the psalm on that phrase stretches the promise across the full span of time too, starting now and carrying no closing date.
