Passage
And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:
And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:
Hebrews 12:17 For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
Hebrews 12:18 For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,
Hebrews 12:19 And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:
Hebrews 12:20 (For they could not endure that which was commanded, And if so much as a beast touch the mountain, it shall be stoned, or thrust through with a dart:
Hebrews 12:21 And so terrible was the sight, that Moses said, I exceedingly fear and quake:)
The verse centers on "sound", "trumpet", "voice", "words", "heard", and "intreated". It is saying that the verse draws attention to "sound" and "trumpet", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "For ye are not come unto the..." into verse 20's "For they could not endure that which...", so "sound" and "trumpet" belong inside that flow. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "sound" and "trumpet" with trust shaped by these words, not by a vague optimism outside the passage.
