Ephesians 5:3

“But fornication, and all uncleanness, or covetousness, &c.] The apostle proceeds to dehort from several vices, which are unbecoming the dear children and followers of God; and which the love of Christ should constrain them to avoid: the first of these, which is simple “fornication”, is the sin which is committed between single or unmarried persons; and is contrary to the law of God, is a work of the flesh, and is against a man's own body; it renders persons unfit for church communion, brings many temporal calamities upon them, and exposes them to divine wrath, and excludes from the kingdom of heaven, without repentance; and the reason why it is so often taken notice of is, because it was…”

“once named--Greek, "Let it not be even named" (Eph 5:4, Eph 5:12). "Uncleanness" and "covetousness" are taken up again from Eph 4:19. The two are so closely allied that the Greek for "covetousness" (pleonexia) is used sometimes in Scripture, and often in the Greek Fathers, for sins of impurity.

“But fornication - A “common” vice among the pagan then as it is now, and one into which they were in special danger of falling; see Romans 1:29 note; 1 Corinthians 6:18 note. And all uncleanness - Impurity of life; see the notes on Romans 1:24; compare Romans 6:19; Galatians 5:19; Ephesians 4:19; Colossians 3:5. Or covetousness - The “connection” in which this word is found is remarkable. It is associated with the lowest and most debasing vices, and this, as well as those vices, was not once to be “named” among them. What was Paul’s estimate then of covetousness? He considered it as an odious and abominable vice; a vice to be regarded in the same light as the most gross sin, and as wholly to…”

“But let not any impure love be even named or heard of among you - Keep at the utmost distance from it, as becometh saints. Ephesians 5:4”

“5:3-5 God’s people (literally holy ones) must have a holy lifestyle, avoiding the immorality common among unbelievers (cp. 4:19; Col 3:5).”
