Charles Ellicott Commentary Job 36:29

"Yea, can any understand the spreadings of the clouds, The thunderings of his pavilion?" — Job 36:29 (ASV)

The spreading of the clouds — that is, how the clouds are spread over the heavens, and heaped up one upon the other like mountains in the skies when the storm gathers.

Or the noise of His tabernacle? — Or the thunderings of His pavilion (Psalms 18:12).
