Be it known, therefore, &c. Having reproved the unbelieving and disobedient among his hearers, he assured them that the salvation of God, which they despised and seemed to fortify themselves against, was sent unto the Gentiles Namely, more especially from that time; and that they would hear and embrace it, and so inherit the blessings which these Jews rejected. His words imply, that he would, from that day forward, turn to the Gentiles; and would seek, in their faith and obedience, his consolation under that grief which the infidelity of his brethren gave him. Before this, it must be observed, no apostle had been at Rome. St. Paul was the first. And when he had said these words The last, it seems, that he now uttered among them; the Jews departed Out of the place, not being prevailed upon to receive Jesus as the Messiah; and had great reasoning Greek, συζητησιν, disputations; among themselves Some thinking there was considerable weight in what Paul had urged to defend the gospel, while others, still retaining their sinful and inveterate prejudices against it, were enraged, and spake of him and his arguments with great contempt and indignation.
