Hebrews 12:26
“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 to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
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:
