Isaiah 49:6

And He, Jehovah, said, It is a light thing that Thou shouldest be My Servant to raise up the tribes of Jacob and to restore the preserved of Israel, those whom the Lord had chosen for His own out of the descendants of the patriarchs, Cf Matthew 15:24; I will also give Thee for a light to the Gentiles, Isaiah 60:3, that Thou mayest be My Salvation unto the end of the earth, the Servant of Jehovah being the Savior of the whole world, the heathen being fellow-citizens with the saints and of the household of God. Although the children of Israel were the chosen people of the Lord, His first-born son, it remains true, nevertheless, that there is no difference between the Jew and the Greek; for the same Lord over all is rich unto all that call upon Him, Romans 10:12.
