Also, can any understand the spreadings of the clouds? - The out spreading - the manner in which they expand themselves over us. The idea is, that the manner in which the clouds seem to “spread out,” or unfold themselves on the sky, could not be explained, and was a striking proof of the wisdom and power of God. In the early periods of the world, it could not be expected that the causes of these phenomena would be known. Now that the causes “are” better known, however, they do not less indicate the wisdom and power of God, nor are these facts less fitted to excite our wonder. The simple and beautiful laws by which the clouds are suspended; by which they roll in the sky; by which they spread themselves out - as in a rising tempest, and by which they seem to unfold themselves over the heavens, should increase, rather than diminish, our conceptions of the wisdom and power of the Most High.
Or, the noise of his tabernacle - Referring, doubtless, to thunder. The clouds are represented as a tent or pavilion spread out for the dwelling of God (compare the notes at Isaiah 40:22), and the idea here is, that the noise made in a thunder-storm is in the unique dwelling of God. Herder well expresses it, “The fearful thunderings in his tent,” compare Psalms 18:11 -
He made darkness his secret place,
His pavilion round about him were dark waters and thick clouds of the skies.
The sense here is, who can understand and explain the cause of thunder? The object of Elihu in this is, to show how great and incomprehensible is God, and nature furnishes few more impressive illustrations of this than the crash of thunder.
