Hebrews 12:25-26

King James Version

²⁵ 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:

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.
