Musar על דניאל 3:19

The sense of smell also commands four qualities -- Anger, Good-will, Jealousy, and Wide-awakedness. Anger is attributed to the sense of smell, as it is said (Jud. xiv. 19), "And his nose (anger) was kindled": anger, indignation, and wrath appear mostly in connection with the nose, as it is said (Dan. iii. 19), "Then was Nebuchadnezzar full of fury, and the form of his nose (visage) was changed." Good-will consists in the tranquility of the thoughts, which are in the brain, and it is not altered by an "illness" of the sense of smell, though the nearest among the senses affecting it. Concerning good-will it is said (Prov. xvi. 15), "In the light of the king's nose (countenance) is life, and his favor is as a cloud of the latter rain."
