Commentary for II Samuel 22:9

Smoke rose from His Nostrils. Such is the manner of an angry person, smoke comes out of his nostrils and so [we find], "Smoke has risen from My nostrils."¹¹Yeshayohu 65:5. This is always the meaning of the words "Anger of the nose," the nose flares and lets out air.

Fire from His Mouth consumed [the wicked]. Through the decree utterred from His Mouth fire [came forth] and consumed the wicked.
