Answer:
Paul said that the Gentiles will listen to the message of Salvation, to the leading men of the Jews.
Step-by-step explanation:
The reference of this instance can be found in the book of Acts 28:17-31.
After the ship, on which Paul was traveling, was wintered on an island, he was taken to Rome. So, when he arrived there he called the leaders of Jews to preach the message of salvation, that comes from believing in Christ. After Paul explained to them the message of Christ, some Jews believed on the message while others rejected.
To this Paul said to the leading men of the Jews that the message of salvation will be listened by Gentiles. [Acts 28:28] (Paul was appointed by God to preach among the Gentiles.)
Thus according to Paul, Gentiles will listen to the message of salvation.
