Isaiah 49:2-4

2And He has made My mouth like a sharp sword; In the shadow of His hand He has hidden Me, And made Me a polished shaft; In His quiver He has hidden Me.”

3“And He said to me, ‘You are My servant, O Israel, In whom I will be glorified.’

4Then I said, ‘I have labored in vain, I have spent my strength for nothing and in vain; Yet surely my just reward is with the Lord, And my work with my God.’ ”
