Isaiah 66:12 - Matthew Poole's English Annotations on the Holy Bible

That this promise respects the times of the Messias seems plain, not only from the consideration that no history giveth us any account of any great or long peace or prosperity the Jews had before that time, nor indeed then, if we understand it not of a spiritual gospel peace, which Christ preached to them that were nigh as well as to those afar off, Ephesians 2:17. It also appears from the mention of the glory of the Gentiles as a flowing stream, which can hardly be understood of any thing but Christ, and the preaching of the gospel to the Gentiles. But I leave it to the issues of Providence to expound and determine whether the prophecy of this text doth not relate to a further conversion and calling of the Jews than hath yet been seen. When Christ was revealed to the Jews, not those only of the Gentiles, but those of the Jews who belonged to God's election sucked gospel doctrine; the Gentiles were borne upon the sides of Jerusalem, and dandled upon her knees, as first hearing from the apostles, who were some of the daughters of Jerusalem, members of the Jewish church, the glad tidings of salvation.
