2 Samuel 22:12

And he made darkness pavilions round about him, dark waters, and thick clouds of the skies.

Cross-reference

2 Samuel 22:10 describes dark clouds under God's feet; verse 12 adds that darkness was his canopy.

Psalm 18:11 repeats this nearly verbatim — the same image of God's canopy of dark rain clouds in the parallel song.

Psalm 18:12 continues the theophany — from darkness to brightness with hailstones and lightning, the next verse in the parallel.

Psalm 97:2 also describes clouds and thick darkness surrounding God — a similar theophanic setting of divine majesty.
