Isaiah 40:31
King James Version
“But they that wait upon the LORD shall renew strength; they shall mount up with wings as eagles; they shall run, and not be weary; they shall walk, and not faint.”
Context
28Hast thou not known? hast thou not heard, the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? no searching of his understanding.
29He giveth power to the faint; and to no might he increaseth strength.
30Even the youths shall faint and be weary, and the young men shall utterly fall:
31But they that wait upon the LORD shall renew strength; they shall mount up with wings as eagles; they shall run, and not be weary; they shall walk, and not faint.
