John Calvin on Hebrews 12:24

24. And to Jesus the Mediator, etc. He adds this in the last place, because it is he alone through whom the Father is reconciled to us, and who renders his face serene and lovely to us, so that we may come to him without fear. At the same time he shows how Christ becomes our Mediator, even through his own blood, which after the Hebrew mode of speaking he calls the blood of sprinkling, which means sprinkled blood; for as it was once for all shed to make an atonement for us, so our souls must be now cleansed by it through faith. At the same time the Apostle alludes to the ancient rite of the Law, which has been before mentioned.

That speaketh better things, etc. There is no reason why better may not be rendered adverbially in the following manner, — “Christ’s blood cries more efficaciously, and is better heard by God than the blood of Abel.” It is, however, preferable to take the words literally: the blood of Christ is said to speak better things, because it avails to obtain pardon for our sins. The blood of Abel did not properly cry out; for it was his murder that called for vengeance before God. But the blood of Christ cries out, and the atonement made by it is heard daily. See Appendix X 2.

Hebrews Chapter 12:25-29

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:

25. Videte ne asperenemini loquentem; nam si illi, qui aspeernati sunt eum qui loquebatur in terra, non effugerunt, multo magic nos si aversemur loquentem e coelis;

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.

26. Cujus vox tune terram concussit, nunc autem denuntiavit, dicens, Adhuc semel ego moveo non solum terram, sed etiam coelum.

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.

27. Illud autem, Adhuc semel, significat eurum quae concutiuntur translationem, ut maneant quae non concutiuntur.

28. Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:

28. Quare regnum quod non concutitur apprehendentes, habemus (alias, habeumus) gratiam: per quam colamus Deum, placentes illi cum reverentia et religione:

29. For our God is a consuming fire.

29. Deus enim noster ignis consumens est.
