Romans 10:5

Verse 5. For Moses describeth, etc. This is found in Le 18:5, "Ye shall therefore keep my statutes and my judgments, which if a man do he shall live in them." This appeal is made to Moses, both in regard to the righteousness of the law and that of faith, in accordance with the usual manner of Paul to sustain all his positions by the Old Testament, and to show that he was introducing no new doctrine. He was only affirming that which had been long before taught in the writings of the Jews themselves. The word describeth is, literally, writes, (grafei) a word often used in this sense. The righteousness, etc. The righteousness which a perfect obedience to the law of God would produce.
