Isaiah 49:5-6

5And now saith Jehovah that formed me from the womb to be his servant, to bring Jacob again to him, and that Israel be gathered unto him (for I am honorable in the eyes of Jehovah, and my God is become my strength); 6yea, he saith, It is too light a thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.
