Yes. The antediluvian or pre-Adamic races also answer the question: Of whom was Jesus speaking when He said "I have other sheep about whom you know nothing?"
And other sheep I have, that are not of this fold: them also I must bring, and they shall hear my voice, and there shall be one fold and one shepherd. - John 10:16
And other sheep I have, &c. Other sheep, i.e, those who will be My sheep. This is spoken by anticipation. He means the Gentiles, and thus predicts their call and conversion, to show that He was to be the King and Shepherd of all nations, just as up to this time He had been of the Jews: and that, consequently, He did not care (comparatively) whether the Jews (few as they were in number) would be unbelieving and rebellious, since He was about to put countless Gentiles in their place. So Rupertus, who adds, "and they will hear My voice," striking quietly at the Jews.
