That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
Ver. 22. That ye put off, &c.] As the beggar puts off his rags, as the master puts off his bad servant, as the porter puts off his burden, as the husband puts off his lewd wife, as the serpent his slough, or as the captive maid, when she was to be married, put off the garments of her captivity,Deuteronomy 21:13 .
The old man which is corrupt] Sin is said to be the old man, because it lives in man so as sin seems to be alive and the man dead; and because God will take notice of nothing in the sinner but his sin.
According to the deceitful lusts] Sin, though at first it fawn upon a man, yet in the end (with Cain's dog lying at the door) it will pluck out the very throat of his soul, if not repented of. Like the serpent, together with the embrace, it stings mortally. Hence the ruler's meat is called deceivable, Proverbs 23:3. There being a deceitfulness in sin, Hebrews 3:13, a lie in vanity, John 2:8. Lust hath a deceit in it, as here.
