KJV:
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:
NASB:
and to the blast of a trumpet and the sound of words which sound was such that those who heard begged that no further word be spoken to them.
KJV:
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:
NASB:
See to it that you do not refuse Him who is speaking. For if those did not escape when they refused him who warned them on earth, much less will we escape who turn away from Him who warns from heaven.
