Jews by nature; born Jews, not only proselyted to the Jewish religion, (and so under an obligation to the observation of the Jewish law), but of the seed of Abraham, and so under the covenant made with him and his seed, as he was the father of the Jewish nation. Not sinners of the Gentiles: the Gentiles were ordinarily called by the Jews sinners; though it appeareth that there were divers of them worshippers of the true God, and came up to Jerusalem to worship; for whose sake there was a peculiar court allotted in the temple, called: The court of the Gentiles. Yet not being under the obligation of the Jewish law, they went under the denomination of sinners by the Jews; and the most of the Gentiles were really sinners, and that eminently, (for such the word here used ordinarily signifieth), as the apostle describeth their manners, Romans 1:29-31.
