A.T. Robertson Commentary Ephesians 5:3

"But fornication, and all uncleanness, or covetousness, let it not even be named among you, as becometh saints;" — Ephesians 5:3 (ASV)

Or covetousness (η πλεονεξια). In bad company surely. Debasing like sensuality.

As becometh saints (καθως πρεπε αγιοις). It is "unbecoming" for a saint to be sensual or covetous.
