John Calvin on Romans 2:9-10

9. To the Jew first, etc. He simply places, I have no doubt, the Jew in opposition to the Gentile; for those whom he calls Greeks he will presently call Gentiles. But the Jews take the precedence in this case, for they had, in preference to others, both the promises and the threatenings of the law; as though he had said, “This is the universal rule of the divine judgment; it shall begin with the Jews, and it shall include the whole world.”

Romans 2:11-13

11. For there is no respect of persons with God.

11. Siquidem non est acceptio personarum apud Deum.

12. For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;

12. Quicunque enim sine Lege peccaverunt sine Lege etiam peribunt; quicunque vero in Lege peccaverunt per Legem judicabuntur.

13. (For not the hearers of the law are just before God, but the doers of the law shall be justified.

13. Non enim Legis auditores justi sunt apud Deum, sed qui Legem faciunt justificabuntur.
