Isaiah 40:28-31

New International Version

²⁸ Do you not know?
    Have you not heard?^(A)
The Lord is the everlasting^(B) God,
    the Creator^(C) of the ends of the earth.^(D)
He will not grow tired or weary,^(E)
    and his understanding no one can fathom.^(F)
29 He gives strength^(G) to the weary^(H)
    and increases the power of the weak.
³⁰ Even youths grow tired and weary,
    and young men^(I) stumble and fall;^(J)
31 but those who hope^(K) in the Lord
    will renew their strength.^(L)
They will soar on wings like eagles;^(M)
    they will run and not grow weary,
    they will walk and not be faint.^(N)
