The old man
See on Rom 6:6. Compare Col 3:9.
Which is corrupt (τὸν φθειρόμενον)
The A.V. misses the force of the participle. The verb is passive, which is being corrupted, and marks the progressive condition of corruption which characterizes “the old man.” Rev., correctly, waxeth corrupt.
According to the deceitful lusts (κατὰ τὰς ἐπιθυμίας τῆς ἀπάτης).
Rev., correctly, lusts of deceit. On the vicious rendering of similar phrases in A.V., see on Eph 1:19. Deceit is personified.
