Psalms 90:8

Instead of -hiding His face" from their sins He sets them all before Him, and drags them all to light. Elsewhere -the light of God's countenance" denotes His favour; here a slightly different word, lit. the luminary of Thy face, is used to denote His Presence as a searching light from which nothing can be hid. Our secret[sin is rather the inward sin of the heart unseen by man but known to God (Psalms 44:21, a cognate word), than sin of which the sinner is himself unconscious (Psalms 19:12), though this may be included.
