Isaiah 50:2, 7-10

When I came, why was there no one? When I called, why was there no one to answer? Was my arm too short to ransom you? Do I lack the strength to rescue you? By a mere rebuke I dried up the sea, I turn rivers into a desert; their fish rot for lack of water and die of thirst.

Because the Sovereign Lord helps me, I will not be disgraced. Therefore have I set my face like a flint, and I know I will not be put to shame. He who vindicates me is near. Who then will bring charges against me? Let us face each other! Where is my accuser? Let him confront me! It is the Sovereign Lord who helps me. Who is he that will condemn me? They will all wear out like a garment; the moths will eat them up. Who among you fears the Lord and obeys the word of His servant? Let him who walks in the dark, who has no light, trust in the name of the Lord and rely on his God.
