Isaiah 40:28-31 CSB
Do you not know?
Have you not heard?
The LORD is the everlasting God,
the Creator of the whole earth.
He never becomes faint or weary;
there is no limit to his understanding.
He gives strength to the faint
and strengthens the powerless.
Youths may become faint and weary,
and young men stumble and fall,
but those who trust in the LORD
will renew their strength;
they will soar on wings like eagles;
they will run and not become weary,
they will walk and not faint.
