Isaiah 49:2-4

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.
