That ye put away (apothesthai). Second aorist middle infinitive of apotithēmi with the metaphor of putting off clothing or habits as apothesthe in Col 3:8 (which see) with the same addition of “the old man” (ton palaion anthrōpon) as in Col 3:9. For anastrophēn (manner of life) see note on Gal 1:13.
Which waxeth corrupt (ton phtheiromenon). Either present middle or passive participle of phtheirō, but it is a process of corruption (worse and worse).
