Hebrews 12:24 (KJV)

And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:

(For they could not endure that which was commanded, And if so much as a beast touch the mountain, it shall be stoned, or thrust through with a dart:

And so terrible was the sight, that Moses said, I exceedingly fear and quake:)

But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,

To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,

See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven:

Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven.

And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain.

Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:

For our God is a consuming fire.
