ACV(i)
25 Watch, that ye not refuse him who speaks. For if those men did not escape, having refused him who spoke a divine message on earth, much more we, those who turn away from him from the heavens,
26 whose voice then shook the earth. But now he has promised, saying, Yet once, I shake not only the earth, but also the heaven.
27 And the, Yet once, signifies the removal of the things being shaken-as of things that were made-so that the things not being shaken may remain.
28 Therefore, receiving an immovable kingdom, we may have grace, through which we may serve God acceptably with reverence and awe.
