Hebrews 12:25-27 Revised Geneva Translation (RGT)
25 See that you do not despise Him Who speaks. For if those did not escape who refused Him who spoke on earth, much more so shall we not escape if we turn away from Him Who speaks from Heaven.
26 His voice shook the earth then. And now He has declared, saying, “Yet once more will I shake, not the earth only, but also Heaven.”
27 And this, “Yet once more” signifies the removing of those things which are shaken (as in things which are made) so that the things which are not shaken may remain.
