Is 40:27-31

27Why, O Jacob, do you say,^*

and declare, O Israel,

“My way is hidden from the LORD,

and my right is disregarded by my God”?

28Do you not know?

Have you not heard?

The LORD is God from of old,

creator of the ends of the earth.

He does not faint or grow weary,

and his knowledge is beyond scrutiny.

29He gives power to the faint,

abundant strength to the weak.

30Though young men faint and grow weary,

and youths stagger and fall,

31They that hope in the LORD will renew their strength,

they will soar on eagles’ wings;

They will run and not grow weary,

walk and not grow faint.
