John 10:16 - Matthew Poole's English Annotations on the Holy Bible

And other sheep I have which are not of this fold; our Saviour meaneth the Gentiles, who belonged not to the Jewish state and church, so were not under the same laws and government; for, 1 John 2:2, he was not only a propitiation for the sins of the Jews, but for the sins of the whole world: he calleth those sheep, because the Lord knew who were his from eternity; and they were sheep in the counsels of God, and they were suddenly to be made his sheep by calling, the gospel being soon to be preached to all nations. Then also (saith he) I must bring in; it is so written in God's book, the promises and prophecies to that purpose must be fulfilled. They shall not only hear the voice and sound of my gospel, though going out of Zion, yet not terminated in Zion; but they shall embrace, receive, and believe that joyful sound. And there shall be one fold, and one shepherd; and there shall be but one church; as I am one Shepherd, so there shall be but one flock of sheep; one body, one Spirit, one hope of our calling, one Lord, one faith, one baptism, as there is one God and Father of all, as the apostle speaketh, Ephesians 4:4-6.
