Isaiah 49:2-4

2He made my words of judgment as sharp as a sword. He has hidden me in the shadow of his hand. I am like a sharp arrow in his quiver.

3He said to me, “You are my servant, Israel, and you will bring me glory.”

4I replied, “But my work seems so useless! I have spent my strength for nothing and to no purpose. Yet I leave it all in the Lord’s hand; I will trust God for my reward.”
