Ephesians 4:22

“That ye put off concerning the former conversation, the old man, &c.] Which is the corruption of nature; why this is called a man, and an old man, (see Gill on “ <450606>Romans 6:6”), the putting him off, is not a removing him from the saints, nor a destroying him in them, nor a changing his nature; for he remains, and remains alive, and is the same old man he ever was, in regenerate persons; but it is a putting him off from his seat, and a putting him down from his government; a showing no regard to his rule and dominion, to his laws and lusts, making no provision for his support; and particularly, not squaring the life and conversation according to his dictates and directions; and…”

Concerning the former conversation - The word “conversation” here means conduct - as it commonly does in the Bible; see the notes, 2 Corinthians 1:12. The meaning here is, “with respect to your former conduct or habits of life, lay aside all that pertained to a corrupt and fallen nature.” You are not to lay “everything” aside that formerly pertained to…”
