From Spurgeon’s Treasury of David – Psalm 2 – Explanatory Notes and Quaint Sayings.
Verse 12. “If his wrath be kindled but a little;” the Hebrew is if his nose or nostril be kindled but a little; the nostril, being an organ of the body in which wrath shows itself, is put for wrath itself. Paleness and snuffling of the nose are symptoms of anger. In our proverbials, to take a thing in snuff is to take it in anger. Joseph Caryl.
