But the unbelieving Jews stirred up the Gentiles, and made their minds evil affected against the brethren. Stirred up the Gentiles - Των εθνων, Such as were mere heathens, and thus distinguished from the Jews, and the Greeks who were proselytes.
Evil affected - Εκακωσαν, Irritated or exasperated their minds against the brethren, the disciples of Christ; one of their appellations before they were called Christians at Antioch. See on Acts 11:26 (note).
