Matthew Poole and continuators on Acts 11:20

20 And some of them were men of Cyprus, and Cyrene, which when they were come to Antioch, spake unto the Grecians, preaching the Lord Jesus.

They were such as were born in Cyprus and Cyrene, but had their habitation in Ierusalem; and now upon the Persecution there, fled unto Antiock.

Which by this means in time became the Ierusalem of the Gentile-Christians, whither their greatest resort was.

Here they of the dispersion taught not only such Hellenists as are spoken of, Chap. 6.1. who were born of Hebrew Parents, tho living out of the Country of Iudea; but such also amongst the Gentiles (who are generally called Greeks since Alexander's time, who conquered all those Nations round about, and brought in his own Language amongst them) who forsaking Idolatry, and worshipping the True God, were called [non-Latin text not transcribed], Devout or Religious persons, such as Cornelius is said to be, Chap. 10.2. And thus God by degrees brought in the knowledg of himself, and his Son Jesus Christ.

Which knowledg only is that which is necessary unto Salvation; and that only which Saul determined to know, 1 Cor. 2.2.
