Acts 13:45-47

But when the Jews saw the crowds, they were filled with jealousy and began contradicting the things said by Paul, and were slandering him. And [at the same time] Paul and Barnabas spoke out boldly and confidently, saying, “It was necessary that God’s message [of salvation through faith in Christ] be spoken to you [Jews] first. Since you repudiate it and judge yourselves unworthy of eternal life, now we turn to the Gentiles. For that is what the Lord has commanded us, saying, ‘I HAVE PLACED YOU AS A LIGHT FOR THE GENTILES, SO THAT YOU MAY BRING [the message of eternal] SALVATION TO THE END OF THE EARTH.’ ” [Is 49:6]
