pursuing a course of action. “After” is opisō (ὀπισω), which is used of the act of joining a certain person as an attendant and follower, of running after a thing that one lusts for. “Flesh” is sarx (σαρξ), and here has reference to the totally depraved nature. The picture in the Greek therefore is of these Libertines pursuing after the evil nature, eager to follow its behests. “Lust” is epithumia (ἐπιθυμια), “passionate desire, a craving.” “Uncleanness” is miasma (μιασμα), “that which defiles.”
