Charles Ellicott Commentary Job 37:11

"Yea, he ladeth the thick cloud with moisture; He spreadeth abroad the cloud of his lightning:" — Job 37:11 (ASV)

He wearieth the thick cloud. Also He loads the thick cloud with moisture and makes it charged with rain.

He scattereth the cloud of His lightning, that is, which contains His lightning.

Others render, “Yea, the bright sun wearieth out (disperseth) the thick cloud; it scattereth the cloud that holds His lightning. And it (the cloud) is turned round about by His counsels, that they may do His purpose, even all which He commandeth them, upon the face of the habitable world.”

Whether for correction, or for His land generally, or whether He causes the rain to come as a special mercy—these are the various purposes for which God reserves His showers.
