Isaiah 40:28-30

New Revised Standard Version Updated Edition

²⁸ Have you not known? Have you not heard?
The Lord is the everlasting God,
    the Creator of the ends of the earth.
He does not faint or grow weary;
    his understanding is unsearchable.^(A)
29 He gives power to the faint
    and strengthens the powerless.^(B)
30 Even youths will faint and be weary,
    and the young will fall exhausted,
