Hear attentively the noise of his voice, and the sound that goeth out of his mouth. Hear attentively - "Hear with hearing." The words seem to intimate that there was actually at that time a violent storm of thunder and lightning, and that the successive peals were now breaking over the house, and the lightning flashing before their eyes. The storm continued till Elihu had finished, and out of that storm the Almighty spoke. See the beginning of the succeeding chapter, Job 38 (note).
The noise of his voice - The sudden clap.
And the sound that goeth out - The peal or continued rattling, pounding, and thumping, to the end of the peal. The whole is represented as the voice of God himself, and the thunder is immediately issuing from his mouth.
