Isaiah 49:4-7

4Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: yet surely my judgment is with Yhwh, and my work with my God.1

5And now, saith Yhwh that formed me from the womb to be his servant, to bring Jacob again to him, Though Israel be not gathered, yet shall I be glorious in the eyes of Yhwh, and my God shall be my strength.2 6And he 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: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.34 7Thus saith Yhwh, the Redeemer of Israel, and his Holy One, to him whom man despiseth, to him whom the nation abhorreth, to a servant of rulers, Kings shall see and arise, princes also shall worship, because of Yhwh that is faithful, and the Holy One of Israel, and he shall choose thee.5
