Isaiah 40:28-31

Don't you know?
Haven't you heard?
The eternal God, the Lord, the Creator of the ends of the earth,
doesn't grow tired or become weary.
His understanding is beyond reach.
He gives strength to those who grow tired
and increases the strength of those who are weak.
Even young people grow tired and become weary,
and young men will stumble and fall.
Yet, the strength of those who wait with hope in the Lord
will be renewed.

They will soar on wings like eagles.

They will run and won't become weary.

They will walk and won't grow tired.
