Heb 12:25

“"See that ye refuse not Him that speaketh"; that is, that ye reject Him not. "For if they escaped not who refused Him that spake on earth." Whom does he mean? Moses, I suppose. But what he says is this: if they, having "refused Him" when He gave laws "on earth, did not escape," how shall we refuse Him, when He gives laws from Heaven? He declares here not that He is another; far from it. He does not set forth One and Another, but He appears terrible, when uttering His Voice "from Heaven." It is He Himself then, both the one and the other: but the One is terrible. For he expresses not a difference of Persons but of the gift. Whence does this appear? "For if they escaped not," he says, "who refused Him that spake on earth, much more shall not we escape, if we turn away from Him that speaketh from heaven." What then? Is this one different from the other? How then does he say, "whose voice then shook the earth"? For it was the "voice" of Him who "then" gave the Law, which "shook the earth."”

“"The one who warned them on earth" can be understood to mean the one promising them earthly things that will pass away: the land flowing with milk and honey, the conquest of enemies, goodly offspring and long life. But from heaven speaks the one who promises heaven itself as an inheritance, who graciously bestows the enjoyment of that unspeakable and eternal glory. Or "warned them on earth" can be said to mean that bodily purifications pervaded nearly everything of the law given through Moses. But the giving of the law that took place through Christ is a cleansing and illumination of the soul for us. Then "on earth" are the things proclaimed, because they are lowly and applied to the body made of dirt; and the things of the New Testament are "from heaven" because they are divine and exalted and cleanse the soul in a truly divine manner and bear it up into heaven.”

“"Do not turn away" through unbelief in His promises and despair. Who then is "the one speaking," if not Christ? For if His Blood speaks, then how much more He Himself. "If those who did not listen to the one who spoke on earth did not escape punishment." What did they not escape? Punishment, destruction. By "the one who spoke on earth" he means Moses, or even God, who descended from heaven but nevertheless spoke on earth through Moses. For on Mount Sinai He spoke, that is, He conversed, discoursed, and established everything. "So much more shall we not escape, if we turn away from Him who speaks from heaven." That is, Christ, prophesying from heaven, that is, after His ascension, having granted us the law through the Spirit. He did not say that one law existed then and now another, but the manner of the lawgiving has a distinction. For then, speaking on earth, He gave the law; but now, as has been said, after the ascension. Therefore He would be even more fearsome. But He was not one then and another now. Listen further to him himself.”

“713. – After describing the condition of both testaments, the Apostle now argues from this description and does two things: first, he argues; secondly, he draws the conclusion (v. 28). In regard to the first he does two things: first, he prefaces his intention; secondly, he argues to his conclusion (v. 25b). 714. – He says, therefore: Thus we have said that the blood of Christ speaks more graciously than the blood of Abel. See to it, therefore, that you do not refuse, i.e., despise, him that is speaking, i.e., fulfill what he says. But the blood of Christ says two things to us: first, it speaks by reminding us of His favor, by which He remitted our sins. Therefore, one who sins again, despises the one speaking. Furthermore, He speaks by exhorting us to imitate Him: 'Christ suffered for us, leaving you an example to follow in his footsteps' (1 Pt 2:2). Therefore, one who does not take up His cross to follow, refuses the one speaking: 'Today, if you hear his voice, harden not your hearts' (Ps. 94:8); 'This is my beloved Son in whom I am well pleased' (Mt. 17:5). 715. – Then when he says, For if they escaped not, much more shall not we, he argues by comparing the speaking of the Old Testament to that of the New; and this in regard to two things: first, as to the manner of speaking; secondly, as to the efficacy of the speaking. 716. – The manner of speaking, because He spoke upon earth; but here He speaks from heaven. Hence, he says, If they, namely, the ancient fathers, refused him who warned them on earth, namely, Christ: 'For I myself that spoke, behold I am here' (Is. 52:6), namely, by angels or prophets: 'God who at sundry times and in divers manners spoke in time past to the fathers by the prophets' (Heb. 1:1); or him, i.e., the angel through whom the Law was given to Moses: 'Ordained by angels' (Gal. 3:19); 'For if the word spoken by angels became steadfast' (Heb. 2:2): 'This is Moses who was in the church in the wilderness, with the angel who spoke to him on mount Sinai, and with our fathers' (Ac. 7:38) did not escape the vengeance of the divine law: 'The way to escape shall fail them' (Jb. 11:20): 'Every transgression and disobedience received a just recompense' (Heb. 2:2). 717. – The conclusion follows by arguing from the lesser case: If those who refused the one speaking upon earth did not escape, much less shall we escape if we reject him who warns from heaven; because we shall not be able to escape. For the one who speaks to us in the New Testament is Christ already in heaven: 'The Lord Jesus, after he spoke to them, was taken up into heaven' (Mk 16:19); 'From heaven he made you to hear his voice that he might teach you' (Dt. 4:36). Therefore, the doctrine of the Old Testament is the doctrine of Christ speaking on earth for two reasons: because there under the figure of earthly things He spoke of heavenly things; furthermore, He promised earthly things there. But the doctrine of the New Testament is that of Christ speaking from heaven, because we turn earthly things into signs of heavenly things by a mystical interpretation. Likewise, heavenly things are promised in it: 'For your reward is great in heaven' (Mt. 5:12); 'If I speak to you of earthly things and you do not believe; how will you believe, if I speak to you of heavenly things?' (Jn. 3:12).”

“Refuse not then to hearken to him; for if the Jews escaped not God’s severe judgments, for being deaf to his admonitions, given by an Angel to Moses on Mount Sinai, and by him to the people, much less shall we escape, if we turn away our minds, and harden our hearts against the instructions of our Redeemer, who came from heaven to speak to us, and teach us the way to our eternal salvation. (Witham)”

“refuse not--through unbelief. him that speaketh--God in Christ. As the blood of sprinkling is represented as speaking to God for us, Heb 12:24; so here God is represented as speaking to us (Heb 1:1-2). His word now is the prelude of the last "shaking" of all things (Heb 12:27). The same word which is heard in the Gospel from heaven, will shake heaven and earth (Heb 12:26). who refused him--Greek, "refusing as they did." Their seemingly submissive entreaty that the word should not be spoken to them by God any more (Heb 12:19), covered over refractory hearts, as their subsequent deeds showed (Heb 3:16). that spake--revealing with oracular warnings His divine will: so the Greek. if we turn away--Greek, "we who turn away." The word implies greater refractoriness than "refused," or "declined." him that speaketh from heaven--God, by His Son in the Gospel, speaking from His heavenly throne. Hence, in Christ's preaching frequent mention is made of "the kingdom of the heavens" (Greek, Mat 3:2). In the giving of the law God spake on earth (namely, Mount Sinai) by angels (Heb 2:2; compare Heb 1:2). In Exo 20:22, when God says, "I talked with you from heaven," this passage in Hebrews shows that not the highest heavens, but the visible heavens, the clouds and darkness, are meant, out of which God by angels proclaimed the law on Sinai.”

“"having refused the one warning on earth," or the one who engages in earthly matters, promising the earthly and temporary, flowing with milk and honey, the dominion of enemies, good upbringing, and a long life. "from the one from heaven," he speaks, promising the same heaven as an inheritance, granting the enjoyment of that overwhelming glory and eternity. It is possible to say: On earth, to engage in matters, since almost all of the physical purifications were found in the lawgiving through Moses. The new law given to us through Christ is a cleansing and illumination of the soul. Therefore, those things are said to be on earth, as they are humble and related to the material body. But these things are from heaven, as they are divine and lofty, purifying the soul and elevating it to the heavens.”
