Thy hidden ones— God's hidden or treasured ones, are those faithful ones whom he keeps up safe and precious as his treasures. The Chaldee paraphrase renders it, Thy hidden treasures; and elsewhere, as Dr. Hammond observes, they explain themselves to mean thereby, the habitation of God's presence, or the temple and sanctuary itself.
