John Wesley on 2 Corinthians 2:14

To triumph, implies not only victory, but an open manifestation of it. And as in triumphal processions, especially in the east, incense and perfumes were burned near the conqueror, the apostle beautifully alludes to this circumstance in the following verse: as likewise to the different effects which strong perfumes have upon different persons; some of whom they revive, while they throw others into the most violent disorders.
