In Context

23 the universal gathering; and to the assembly of the firstborn who are registered in heaven; and to God, judge of all; and to the spirits of just men made perfect;

24 and to Jesus, mediator of a new covenant; and to the blood of sprinkling, speaking better than Abel.

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:

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.

27 But this Yet once, signifies the removing of what is shaken, as being made, that what is not shaken may remain.

28 Wherefore let us, receiving a kingdom not to be shaken, have grace, by which let us serve God acceptably with reverence and fear.
