Matthew Poole and continuators on Hebrews 12:25

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:

Here the Spirit closely applieth his former Arguments for their pursuit of Holiness, especially that of Christ's speaking by his Blood to them, by Caution, v. 25, 26, 27. by Counsel, v. 28, 29. He introduceth this Caution with look ye, or take ye heed, a term expressing the things said to be great and weighty, intimating that fear, sollicitude and watchfulness about this great and important concernment of their Souls, Luke 12.15. that they see to it there be no aversion in their Spirits to, no undervaluing or despising of, no dislike or Apostacy from, but a hearing, believing, and obeying Jesus speaking by his Blood all the Gospel-Covenant to us, convincing them of Sin and Guilt that needed his Blood, calling them to Repentance and Faith in his Blood and satisfaction, declaring his Intercession with God for Pardon, Holiness and Glory by it, and so importunes them to follow Holiness which would evidence all this to them.

He inforceth his caution by a rational motive of the danger of their refusal, arguing from the less to the greater; that is, their Ancestors escaped not the Vengeance of God when they refused to hear, believe and obey the Legal Covenant, which he spake on Earth from Mount Sinai, and writ on Tables of Stones, and delivered to Moses on the Mount, and by him communicated it to them, chap. 2.2. and 10.28, 30, 31. Deut. 33.1, 4. Acts 7.51, 53. 1 Cor. 10.1. to 11.

Much more and greater Sinners are all such who turn aside scornfully from Jesus, and not receive his Voice and the Revelation of God's Gospel-Covenant by it, who is God's only begotten Son, and brought it down from the Father's Bosom in Heaven, ch. 1.2. Iohn 1.14, 16, 17, 18. and 3.13. ratified it with his own Blood on Earth; and as the Sin is beyond compare greater, so will the punishment be, and the certainty of its infliction both for Time and Eternity, Matth. 11.24. 2 Thess. 1.7, 8, 9. Heb. 10.26, to 32. There remaining no more Sacrifice for such Sin and Sinners.
