Matthew Poole and continuators on Job 37:2

2. Hear attentively the noise of his voice , and the sound that goeth out of his mouth .

It seems not improbable that whilst Elihu was speaking it Thundred greatly, and that Tempest was begun, wherewith God ushered in his Speech, as it here follows, Chap. 38. 1. and that this occasioned his return to that subject of which he had discoursed before, and his exhortation to them to mind it with deeper attention.

Or, his Voice (to wit, the Thunder, which is called a Voice, Exod. 20. 18▪ and Gods Voice, Psal. 29. 4.) with trembling; because the Thunder is an effect or evidence of God's mighty Power and oft-times of his Anger also.

As the voice (and Thunder is God's Voice) goeth out of Man's Mouth. Or, that is produced by God's word or command, which is oft signified by his Mouth.

Marginal references: Heb. hear in hearing.; Heb. [illegible: 1+ letters]is voice with trembling.
