Isaiah 40: 28-31
28 Don’t you know? Haven’t you heard?
The My God is the eternal God,
creator of the ends of the earth.
He does not get tired or exhausted.
His understanding is beyond human reach,
29 giving strength to the weary
and reviving the exhausted.
30 Young people will get tired and tired,
the young men will surely stumble;
31 but those who hope in My God
will renew his strength;
they will fly on their wings like eagles;
they will run and will not be tired;
they will walk and will not be tired.
