As they went out, the people begged that these things might be told them the next Sabbath. And after the meeting of the synagogue broke up, many Jews and devout converts to Judaism followed Paul and Barnabas, who, as they spoke with them, urged them to continue in the grace of God.
The next Sabbath almost the whole city gathered to hear the word of the Lord. But when the Jews saw the crowds, they were filled with jealousy and began to contradict what was spoken by Paul, reviling him. And Paul and Barnabas spoke out boldly, saying, “It was necessary that the word of God be spoken first to you. Since you thrust it aside and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles. For so the Lord has commanded us, saying,
“‘I have made you a light for the Gentiles, that you may bring salvation to the ends of the earth.’”
And when the Gentiles heard this, they began rejoicing and glorifying the word of the Lord, and as many as were appointed to eternal life believed. And the word of the Lord was spreading throughout the whole region. But the Jews incited the devout women of high standing and the leading men of the city, stirred up persecution against Paul and Barnabas, and drove them out of their district. But they shook off the dust from their feet against them and went to Iconium. And the disciples were filled with joy and with the Holy Spirit. (Acts 13:42-52)
It was right for the Jews to be told the word of the Lord by Paul and before the non-Jews, because it was through the Jews that God had chosen to enlighten the whole world by revealing the treasure of his plan of salvation to them first.
