Isaiah 40:27 (KJV)

It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:

That bringeth the princes to nothing; he maketh the judges of the earth as vanity.

Yea, they shall not be planted; yea, they shall not be sown: yea, their stock shall not take root in the earth: and he shall also blow upon them, and they shall wither, and the whirlwind shall take them away as stubble.

To whom then will ye liken me, or shall I be equal? saith the Holy One.

Lift up your eyes on high, and behold who hath created these things, that bringeth out their host by number: he calleth them all by names by the greatness of his might, for that he is strong in power; not one faileth.

Hast thou not known? hast thou not heard, that the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.

He giveth power to the faint; and to them that have no might he increaseth strength.

Even the youths shall faint and be weary, and the young men shall utterly fall:

But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
