Commentary on Ephesians 4:29

Let no corrupt communication proceed - see the notes on 1 Corinthians 15:33 . The word rendered "corrupt" (σαπρος sapros) means bad, decayed, rotten, and is applied to putrid vegetable or animal substances. Then it is applied to a tree that is of a useless character, that produces no good fruit; Matthew 7:17 . Then it is used in a moral sense, as our word "corrupt" is, to denote that which is depraved, evil. contaminating, and may denote here anything that is obscene, offensive, or that tends to corrupt others. The importance of this admonition will be appreciated when it is remembered: (1) that such obscene and filthy conversation prevailed everywhere, and does still among the pagan.
