Have you not heard?
The Lord is the everlasting God,b
the Creator of the whole earth.
He never becomes faint or weary;
there is no limit to his understanding.c
and strengthens the powerless.
and young men stumble and fall,
will renew their strength;d
they will soar on wings like eagles;e
they will run and not become weary,
they will walk and not faint.
