Isaiah 40:29-31

Amplified Bible

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)
