Romans 11:27
For this is my covenant unto them, when I shall take away their sins.
For this is my covenant unto them,.... This is what God has promised to them in covenant, and he will be as good as his word; his covenant will never be broken, it will always remain sure and inviolable; so that there is not only a possibility, and a probability, but even a certainty, of the call and conversion of the Jews; which promise and covenant will have their accomplishment,
when I, saith the Lord,
shall take away their sins: some think that the apostle alludes to
Jeremiah 31:34; others, that he takes this passage out of Isaiah 27:9; where in the Septuagint version the selfsame phrase is used; though it may be no citation, or reference, but the apostle's own words, explaining what is meant by "turning away ungodliness from Jacob",
Romans 11:26; and as before; regards not the taking away of their sins by the sacrifice of Christ, which is done already, and is what the blood of bulls and goats could not do; but of the removing of their sins from themselves, from their consciences, by the application of the blood of Christ, and the imputation of his righteousness.
