John 10:16 I have other sheep, which are not of this fold. I must bring them also, and they will hear my voice. They will become one flock with one shepherd.WEB
Not of this fold. Not Jews. This is a distinct intimation that the gospel was to be preached to the Gentiles--a doctrine extremely offensive to the Jews. This prediction of the Saviour has been strikingly confirmed in the conversion of millions of the Gentiles to the gospel.~Barnes
Christ calls the Gentiles his other sheep, by way of anticipation, because shortly they were to be so, and united together with the believing Jews, into one sheepfold: and whereas he says, he must bring these sheep in, we are to understand it not of a necessity of co-action, but of a necessity of compact; it being a federal agreement betwixt the Father and himself, that both Jew and Gentile should be one flock, inclosed in one fold, and presented to his Father as a glorious church.~Burkitt
Not of this fold; those who as yet knew not God, especially from gentile nations. Isa 56:8.~Family Bible Notes
4. The calling of the Gentiles.~Geneva Bible Footnotes
16. other sheep I have . . . not of this fold: them also I must bring--He means the perishing Gentiles, already His "sheep" in the love of His heart and the purpose of His grace to "bring them" in due time. they shall hear my voice--This is not the language of mere
foresight that they would believe, but the expression of a purpose to draw them to Himself by an inward and efficacious call, which would infallibly issue in their spontaneous accession to Him.
and there shall be one fold--rather "one flock" (for the word for "fold," as in the foregoing verses, is quite different). Jamieson-Fausset-Brown Commentary
And other sheep I have, which are not of this fold. Not Jews, of whom his followers then were, but Gentiles who would soon be called to him. These would hear his voice, enter through the door,
into the same fold as the Jewish Christians, so that there would be "one fold and one shepherd." There is only one Church and one door into it, and one Shepherd over it.~The Peoples New Testament Commentary
i.e. not of the Jewish fold, but Gentiles. Joh 10:4; Isa 56:8; Joh 17:20; Ac 15:7-9.~Scofield
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice: and they shall become one flock, one shepherd. Jesus was speaking to the Jews, who had been frequently spoken of in Scripture as God's flock. The other sheep were Gentiles. They are spoken of as scattered sheep, and not as flocks, because with them there was no unity. Here, as everywhere, the truth breaks through, revealing Christ as the world's Redeemer, who would break down the middle wall of partition between Jew and Gentile, and cause all true worshipers to have a common relationship to one Master.~The Foufold Gospel and Commentary on Acts
For 2,000 years it has been commonly understood that the "other sheep" are Gentiles.
