A light for the nations
When Paul and Barnabas turn to the Gentiles at Pisidian Antioch, they quote Isaiah's words about bringing salvation to the ends of the earth and say that the Lord has commanded them.
He says: βIt is not enough for You to be My Servant, to raise up the tribes of Jacob, and to restore the protected ones of Israel. I will also make You a light for the nations, to bring My salvation to the ends of the earth.β
Isaiah 49:6 speaks of God's Servant as a light for the nations who brings salvation to the ends of the earth; Acts 13:46-47 quotes those words as Paul and Barnabas explain their mission to the Gentiles.
