Isaiah 40:27-31

Amplified Bible

²⁷ 
Why, O Jacob, do you say, and declare, O Israel,
“My way is hidden from the Lord,
And the justice due me escapes the notice of my God”?
²⁸ 
Do you not know? Have you not heard?
The Everlasting God, the Lord, the Creator of the ends of the earth
Does not become tired or grow weary;
There is no searching of His understanding.
²⁹ 
He gives strength to the weary,
And to him who has no might He increases power.^(A)
30 
Even youths grow weary and tired,
And vigorous young men stumble badly,
³¹ 
But those who wait for the Lord [who expect, look for, and hope in Him]
Will gain new strength and renew their power;
They will lift up their wings [and rise up close to God] like eagles [rising toward the sun];
They will run and not become weary,
They will walk and not grow tired.^(B)
