Charles Ellicott Commentary 2 Samuel 22:13

"At the brightness before him Coals of fire were kindled." — 2 Samuel 22:13 (ASV)

Through the brightness. —Rather, Out of the brightness. The psalm (with the same correction) is more full, and perhaps the more exact representation of the original: Out of the brightness before him his thick clouds passed, hail stones and coals of fire.
