Acts 13:46-47

13:46 Both Paul and Barnabas replied courageously, “It was necessary to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we are turning to the Gentiles. 13:47 For this is what the Lord has commanded us: ‘I have appointed you to be a light for the Gentiles, to bring salvation to the ends of the earth.’”
