Isaiah 50:2-5

2Why does no one challenge me when I come? Why does no one respond when I call? Is my hand too weak to deliver you? Do I lack the power to rescue you? Look, with a mere shout I can dry up the sea; I can turn streams into a desert, so the fish rot away and die from lack of water.

3I can clothe the sky in darkness; I can cover it with sackcloth.”

4The sovereign Lord has given me the capacity to be his spokesman, so that I know how to help the weary. He wakes me up every morning; he makes me alert so I can listen attentively as disciples do.

5The sovereign Lord has spoken to me clearly; I have not rebelled, I have not turned back.
