Our comparison of a few olfactory terms reveals some peculiar pattern:

“I hate, I despise your feast days, and I will not smell the scent in your solemn assemblies. Though ye offer Me burnt offerings and your meat offerings, I will not accept them; neither will I regard the peace offerings of your fat beasts. Take thou away from Me the noise of thy songs, for I will not hear the melody of thy viols.” – AMOS
