Vers. 13. (For not the hearers of the Law are just before God, but the doers of the Law shall be justified.)
Reas. 3. Especially intended against the Jews, who according to the rule of Righteousness, cannot be accounted for Righteous before God, even they that are hearers of the Law, unless they perform perfect obedience to the Law, which because neither Jew nor Gentile can do, by consequence neither can they be exempted from deserved condemnation; but on the contrary, especially the Jews, which are hearers of the Law, and do not keep it, are most worthy of judgement.
