“For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them.”
King James Version (KJV)
10:5 For Moses describeth the only righteousness which is attainable by the law, when he saith, The man who doeth these things shall live by them - that is, he that perfectly keeps all these precepts in every point, he alone may claim life and salvation by them. But this way of justification is impossible to any who have ever transgressed any one law in any point. #Lev 18:5|
Ro 10:5 For Moses describeth the righteousness which is by the law. Paul now shows the Jews who cling to the law that the law itself is against the law as a way of securing righteousness. In Le 18:5. The man which doeth those things shall live by them. He who keeps the law in all respects blameless shall have life. But Paul has elsewhere shown that no one can keep the law perfectly (see notes on Ro 2:13 4:15,16 Ga 3:12). That righteousness, then, requires a perfect obedience, a sinless life. What Jew could say that he had never sinned?
