Isaiah: 40:28-31:

Do you not know? Have you not heard?
YHWH is the everlasting God,
the Creator of the ends of the earth.
This God does not faint or grow weary;
with a depth of understanding that is unsearchable.
God gives strength to the weary,
and empowers the powerless.
Young women may grow tired and weary,
young men may stumble and fall,
but those who wait for YHWH
find a renewed power:
they soar on eagles’ wings,
they run and don’t get weary,
they walk and never tire.
