Charles H. Spurgeon on Psalms 135:7

He bringeth the wind out of his treasuries. That is, say some, out of the caves and hollow places of the earth; but I rather conceive that because the wind riseth many times on a sudden, and as our Saviour saith (Joh 3:8), we cannot tell whence it cometh, therefore God is said here to bring it forth, as if he had it locked up in readiness in some secret and hidden treasuries or store houses. —Arthur Jackson.
