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:”
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.
For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,
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:
(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:
And so terrible was the sight, that Moses said, I exceedingly fear and quake:)
