'Voice' in the Bible

Wherefore, even as says the Holy Spirit, To-day if ye will hear his voice,

in that it is said, To-day if ye will hear his voice, do not harden your hearts, as in the provocation;

again he determines a certain day, saying, in David, 'To-day,' after so long a time; (according as it has been said before), To-day, if ye will hear his voice, harden not your hearts.

and trumpet's sound, and voice of words; which they that heard, excusing themselves, declined the word being addressed to them any more:

whose voice then shook the earth; but now he has promised, saying, Yet once will I shake not only the earth, but also the heaven.
