Isaiah prophesied of the power of Jesus.

Isaiah 11:

Out of the stump of David’s family will grow a shoot—
    yes, a new Branch bearing fruit from the old root.
² And the Spirit of the Lord will rest on him—
    the Spirit of wisdom and understanding,
the Spirit of counsel and might,
    the Spirit of knowledge and the fear of the Lord.
³ He will delight in obeying the Lord.
    He will not judge by appearance
    nor make a decision based on hearsay.
⁴ He will give justice to the poor
    and make fair decisions for the exploited.
The earth will shake at the force of his word,
    and one breath from his mouth will destroy the wicked.
⁵ He will wear righteousness like a belt
    and truth like an undergarment.
