That you put off concerning the former way of life the old man, which is corrupt according to the deceitful lusts;
All Commentaries on Ephesians 4:22 Go To Ephesians 4
Jerome
AD 420
The “old nature” whom he tells them to put off has, in my opinion, been aged by wickedness. For, going constantly astray in his former way of life and in the desires of waywardness and acting like a beast in works of corruption, he himself suffers corruption and decay…. But the Word of God kills in such a way as to make the dead one come alive. He then seeks the Lord whom he did not know before his death. He does not corrupt but kills the old man. … As the outer man decays the inner man is renewed. .
