Hebrews 12:18-19

18: For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,

19: 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:

Hebrews 12:26-27

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.

27: 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.
