This verse in the Selah Decoded Version

The mouth is the exit, but the heart is the source, and what it sends out makes the person’s inner condition visible.

What leaves your mouth comes from your heart and bears on your whole person. The mouth gives outward form to what is within; this verse locates defilement in what emerges from that inner source.

WHAT THIS UNDOES

It undoes the belief that a person is made unclean only by what comes from outside: here, what comes out of the heart also matters.

κοινοῖ

koinoi

GROWS FROM

κοιν

koin-

Common or shared; the verb means to make common, and in purity language, to render profane or defiled.

The word translated “defile” belongs to the same word family as “common” and “sharing in common.” The verse describes what comes from the heart as changing the person’s condition, making the inner source visible in the person’s outward life.

ALSO GROWS

koinos: common, shared

κοινός

This is the root family’s basic sense, beneath the verse’s use of the verb for making someone defiled.

koinōnia: sharing in common, participation

κοινωνία

It shows the family’s wider movement from what is shared to what is made common.

ἐκπορευόμενα

ekporeuomena

GROWS FROM

πορευ

poreu-

To go or travel; with ⁨ἐκ⁩ (ek), “out,” the word means to go out or emerge.

The words are pictured as things going out from the heart, with the mouth as their point of emergence. English “proceed” can sound abstract; the Greek gives the verse a movement from an inner source into outward expression.

ALSO GROWS

poreuomai: go, travel

πορεύομαι

It supplies the sense of movement carried by the word for what proceeds from the heart.

poreia: journey, travel

πορεία

This related noun keeps the family’s sense of movement and passage in view.

What is held within a person flows outward through speech and reveals the inner source.

Keep thy heart with all diligence; for out of it are the issues of life.
Proverbs 4:23 · KJVLife’s outward course is pictured as flowing from the heart, the same inner source named in Matthew.
A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
Luke 6:45 · KJVThe heart’s abundance comes out through the mouth, showing the inner-to-outer movement in fuller detail.
Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
James 3:10 · KJVSpeech emerging from the mouth makes the condition of the speaker visible.
A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
Luke 6:45 · KJV

Luke uses the same Greek words for “heart” (⁨καρδία⁩, kardia) and “mouth” (⁨στόμα⁩, stoma), and makes their connection explicit: the mouth speaks from the heart’s abundance. Matthew names what that flow can do to the person; Luke shows the inner store from which it comes.
