Passage
whose voice then shook the earth; but now he has promised, saying, Yet once will *I* shake not only the earth, but also the heaven.
whose voice then shook the earth; but now he has promised, saying, Yet once will *I* shake not only the earth, but also the heaven.
Hebrews 12:24 and to Jesus, mediator of a new covenant; and to [the] blood of sprinkling, speaking better than Abel.
Hebrews 12:25 See that ye refuse not him that speaks. For if those did not escape who had refused him who uttered the oracles on earth, much more we who turn away from him [who does so] from heaven:
Hebrews 12:26 whose voice then shook the earth; but now he has promised, saying, Yet once will *I* shake not only the earth, but also the heaven.
Hebrews 12:27 But this Yet once, signifies the removing of what is shaken, as being made, that what is not shaken may remain.
Hebrews 12:28 Wherefore let us, receiving a kingdom not to be shaken, have grace, by which let us serve God acceptably with reverence and fear.
The verse centers on "whose", "voice", "shook", "earth", "promised", "saying", "once", and "shake". It is saying that the verse draws attention to "whose" and "voice", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "See that ye refuse not him that..." into verse 27's "But this Yet once signifies the removing...", so "whose" and "voice" belong inside that flow. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "whose" and "voice" with trust shaped by these words, not by a vague optimism outside the passage.
