Psalms 18:11

He made darkness his secret place Or, his hiding place: his covert, says Dr. Waterland; his tent, says Chandler. He covered himself with dark clouds. God is frequently represented as surrounded with clouds, in the sacred writings; this representation is peculiarly proper in this place, as thick, heavy clouds, deeply charged, and with lowering aspects, are always the forerunners and attendants of a tempest, and greatly heighten the horrors of the appearance; and the representation of them, as spreading around the Almighty for his pavilion and tent, is truly poetical and grand. And, as storms and tempests in the air are often instruments of the divine displeasure, they are therefore here selected with great propriety as figures of it; and God, who has the whole artillery of the aerial regions at his command, and holds the reins of whirlwinds in his hand, and directs their impetuous course through the world when and how he pleases, is here fifty represented as employing them against his enemies in the day of battle and war.
