Isaiah 49:2-6

2And he hath made my mouth like a sharp sword, he hath concealed me under the shadow of his hand, and he hath made me a polished shaft: in his quiver hath he hidden me.

3And he said unto me, Thou art my servant, Israel, in whom I will glorify myself.

4— And I said, I have laboured in vain, I have spent my strength for nought and in vain; nevertheless my judgment is with Jehovah, and my work with my 1God.

5And now, saith Jehovah, that formed me from the womb to be his servant, that I should bring Jacob again to him; (though Israel be not gathered, yet shall I be glorified in the eyes of Jehovah, and my 2God shall be my strength;)

6— and he saith, It is a small thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel; I have even given thee for a light of the nations, that thou mayest be my salvation unto the end of the earth.
