Hear attentively - Margin, as in Hebrew "hear in hearing;" that is, bear with attention. It has been supposed by many, and not without probability, that the tempest was already seen rising, out of which God was to address Job Job 38, and that Elihu here calls the special attention of his hearers to the gathering storm, and to the low muttering thunder in the distance.
The noise of his voice - Thunder is often represented as the voice of God, and this was one of the most natural of all suppositions when its nature was little understood, and is at all times a beautiful poetic conception; see the whole of Psalm 29:1-11. The word rendered "noise" (רגז rôgez), means properly "commotion," that which is fitted to produce perturbation, or disquiet (see Job 3:17, Job 3:26; Isaiah 14:3), and is used here to denote the commotion, or "raging" of thunder.
And the sound - The word used here (הגה hegeh) means properly a "muttering growling" - as of thunder. It is often used to denote sighing, moaning, and meditation, in contradistinction from clear enunciation. Here it refers to the thunder which seems to mutter or growl in the sky.

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.

Hear attentively the (b) noise of his voice, and the sound [that] goeth out of his mouth.
(b) That is the thunder, by which he speaks to men to waken their dullness, and to bring them to the consideration of his works.

Hear attentively the noise of his voice,.... Of the voice of God in the clouds; and of thunder, which is his voice, Job 40:9. Elihu being affected with it himself, exhorts the company about him to hearken and listen to it, and learn something from it;
and the sound that goeth out of his mouth: as the former clause may have respect to loud thunder, a more violent crack or clap of it; so this may intend some lesser whispers and murmurs of it at a distance; or a rumbling noise in the clouds before they burst; since the word is sometimes used for private meditation. Now the voice of God, whether in his works of nature, or in the dispensations of his providence, or in his word; whether in the thunder of the law, or in the still sound of the Gospel, is to be attentively hearkened to; because it is the voice of God, the voice of the God of glory, majestic and powerful, and is attended with various effects; of which see Psalm 29:3.

Hear attentively--the thunder (noise), &c., and then you will feel that there is good reason to tremble.
sound--muttering of the thunder.

Hear - It is probable that while Elihu was speaking it thundered, and that tempest was begun, wherewith God ushered in his speech. And this might occasion his return to that subject of which he had discoursed before. Voice - The thunder is called God's voice. Because by it God speaks to the children of men, to fear before him. Mouth - That is produced by God's word or command, which is often signified by his mouth.
