Isaiah 49:3-6 NIV

He said to me, “You are my servant, Israel, in whom I will display my splendor.” But I said, “I have labored in vain; I have spent my strength for nothing at all. Yet what is due me is in the LORD’s hand, and my reward is with my God.” And now the LORD says— he who formed me in the womb to be his servant to bring Jacob back to him and gather Israel to himself, for I am honored in the eyes of the LORD and my God has been my strength— he says: “It is too small a thing for you to be my servant to restore the tribes of Jacob and bring back those of Israel I have kept. I will also make you a light for the Gentiles, that my salvation may reach to the ends of the earth.”
