KJV(i)
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.
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.
Hebrews 12:25-27
RKJNT(i)
25 See that you do not refuse him who speaks. For if they did not escape who refused him who warned them on earth, much less shall we escape, if we turn away from him who warns us from heaven.
26 And his voice shook the earth then: but now he has promised, saying, Yet once more I will shake not only the earth, but also heaven.
27 And the words, Yet once more, signify the removal of those things which can be shaken, of created things, that those things which cannot be shaken may remain.
