King James wording
King James Version
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.THE KEY
Speech carries material into another person: it can spread rot, or build what is needed and give favor.
THE MEANING
Speech carries a condition into the person hearing it: it can spoil what it reaches, or build what is needed and extend favor. The hearer is not a passive endpoint; the utterance leaves a real effect in the space of their life.
WHAT THIS UNDOES
It dissolves the belief that words vanish as harmless sounds once spoken. Here an utterance has consequence beyond the speaker: it can spoil or build in another person.
THE ROOT
σαπρός
sapros
GROWS FROM
σηπ-/σαπ- (sēp-/sap-)
To rot or decay; spoiled, decayed.
“rotten word” in this verse is sapros. The word behind “corrupt” pictures decay, making speech itself something that can spoil what it reaches. The verse sets this rot against speech suited to build and give favor.
ALSO GROWS
sēpō: To rot, decay.
σήπω
The verb makes the image active: the speech carries the effect of something spoiling.
sēpsis: Rotting, decay, putrefaction.
σῆψις
This related form names the process of decay that the description of corrupt speech evokes.
οἰκοδομήν
oikodomēn
GROWS FROM
οἰκοδομ
oikodom-
House-building; to build a house.
“building up” in this verse is oikodomēn. The word translated “edifying” is house-building language: good speech is shaped toward constructing what the hearer needs. The verse pictures an utterance leaving structure in the person who receives it.
ALSO GROWS
oikodomeō: To build, build up.
οἰκοδομέω
This verb makes explicit the construction already carried by “edifying.”
oikodomos: Builder.
οἰκοδόμος
The related noun names the one who builds, keeping the passage’s house-building image concrete.
χάριν
charin
GROWS FROM
χαρι
char-
Favor, kindness freely shown.
The purpose of speech is that it may give favor to those who hear. The hearer receives something freely beneficial through the words spoken.
ALSO GROWS
charizomai: To grant favor, give freely.
χαρίζομαι
This verb shows favor as something given, matching the effect the verse names for the hearer.
charisma: A gift freely given, a favor-gift.
χάρισμα
This related word presents favor as a gift received.
THE PATTERN
Words carry consequences into the lives of hearers: they can bring life, offer favor, and serve the work of building.
Death and life are in the hand of the tongue, and those who love it eat its fruit.Let your word always be in favor, seasoned with salt, so that you may know how you must answer each one.What then is it, brothers? When you gather together, each of you has a song, has a teaching, has an unveiling, has a tongue, has a carrying across. Let all things become for the building up.THE THREAD
For we are fellow workers with God. You are God's field; you are God's building.The same Greek house-building word translated “edifying” here appears as “building” there. The connection makes the hearer more than an audience: the one receiving the words is named as God’s building.
