“Let All Mortal Flesh Keep Silence” by Fernando Ortega.

I’ve liked this piece for a long time.  It’s taken from Psalm 139:8-10 (7-12, more broadly).

If to Heaven’s heights I fly
You are still beside me,
Or in death’s dark shadows lie,
You will stay close by me.
If I flee on morning wings
Far across the gray sea,
Even there your hand will lead,
Your right hand will guide me.
