That ye put off; a usual metaphor, taken from garments (implying a total abandoning, and casting away, like a garment not to be put on again): it is oppesed to putting on, Eph_4:24, and is the same as mortifying, Col_3:5, crucifying, Gal_6:14.
Concerning the former conversation; the former heathenish life and manners, Eph_2:2. He shows how they should put off their old man, viz. by relinquishing their old manners; the same as putting off
the old man with his deeds, Col_3:9.
The old man; the pravity of nature, or nature as depraved.
Which is corrupt; or, which corrupteth, i.e. tends to destruction, Gal_6:8; or, which daily grows worse and more corrupt by the fulfilling of its lusts.
According to the deceitful lusts; i.e. which draw away and entice men, Jam_1:14; or which put on a show and semblance of some good, or promise pleasure and happiness, but lurch men’s hopes, and make them more miserable.
