What does Isaiah 11:4 mean?

Instead, he’ll stand up for people who have nothing, and he’ll make fair decisions for those who are powerless. His words will be enough to bring down the violent, and just a breath from him will wipe out those who do evil. Isaiah 11:4 - Modern Text Bible

(He’ll defend the vulnerable and bring justice with authority. His power is in his words and his commitment to what’s right.)
