Job 37:1-5

(1) В¶ At this also my heart trembleth, and is moved out of his place. (2) Hear attentively the noise of his voice, and the sound that goeth out of his mouth. (3) He directeth it under the whole heaven, and his lightning unto the ends of the earth. (4) After it a voice roareth: he thundereth with the voice of his excellency; and he will not stay them when his voice is heard. (5) God thundereth marvellously with his voice; great things doeth he, which we cannot comprehend.

Elihu is here reasoning from the wonders of GOD'S works in the world of nature, in bringing the lightning and rains out of his treasures. And Elihu seems to intimate, that though these are produced, by the LORD'S appointment, from natural causes, yet the world ought to hear the voice of GOD in them, and by them. Witness the LORD'S descent on Mount Sinai, which was accompanied with thunders, and lightenings, and other tremendous signs, to intimate the divine presence. Exodus 19:16. And the Apostle was commissioned by the HOLY GHOST to teach the Church, that those awful signs were figurative also of the alarming nature of the dispensation of the law, to show the gracious and mild dispensation, contrasted to it, in the gospel. Hebrews 12:18.
