And enter not into judgment with thy servant: for in thy sight shall no man living be justified.
And enter not into judgment with thy servant - for my many shortcomings. This shows that the "righteousness" of God, in accordance with which in Psalms 143:1 the Psalmist prays for a favourable answer, is not the righteousness by which the judge exacts strictly all that is due by the sinner. David here deprecates such a strict judgment, as feeling himself unable to "answer Him one of a thousand" charges God could bring against him (Job 9:2-3; Job 14:3-4; Job 15:14; Job 25:4; Psalms 130:3; Psalms 19:12). God enters into strict judgment with all (Matthew 5:26; Matthew 18:27; Matthew 18:34) who are not His true servants; but He never will enter into judgment with His believing and obedient servants; because He has entered into judgment with the Lord, their righteousness and surety, who answers for them: therefore He will not demand an account a second time. He chastens them, but will not give them over unto death.
For in thy sight shall no man living be justified (Romans 3:20) - "no man living," not even the believer; because He too needs daily forgiveness and cleansing away of soils, though he has been once for all washed in the spiritual bath of regeneration upon his believing unto life (John 13:10). In THY sight, who searchest into the heart, and "art of purer eyes than to behold evil" (Habakkuk 1:13).
