Charles Ellicott Commentary 2 Samuel 22:12

"And he made darkness pavilions round about him, Gathering of waters, thick clouds of the skies." — 2 Samuel 22:12 (ASV)

Made darkness pavilions. —Psalms 18:0, more fully, He made darkness his secret place; his pavilion round about him were dark waters. A word appears to have dropped out here, and in the second clause the margin, “binding (or gathering) of waters” is a more exact translation, the word differing in one letter from that used in the psalm.
