Who can discern his errors? Forgive me from hidden errors.
"Who can understand his errors?" A question which is its own answer. It rather requires a note of exclamation than of interrogation. By the law is the knowledge of sin, and in the presence of divine truth, the psalmist marvels at the number and heinousness of his sins.
Who can understand [his] errors? cleanse thou me from secret [faults]. (l) Then there is no reward of duty, but of grace: for where sin is, there death is the reward.
The heavens declare God's glory, but Scripture does far more: it recovers fallen man. Creation would have sufficed if Adam had not sinned, but now divine revelation must do what the works of God alone cannot. The word has its power and excellence from the Lawmaker Himself, and nothing can be added to it or taken away.
