Matthew 15:19 (KJV)

What does Matthew 15:19 mean?

Matthew 15:19 says that evil actions and words come from within a person, specifically from the heart, rather than from outside influences. Jesus lists specific wrongdoings—evil thoughts, murders, adulteries, fornications, thefts, false witness, and blasphemies—as examples of what flows out of the heart.

In this verse, Jesus is speaking to His disciples after a discussion with the Pharisees about ritual handwashing. The Pharisees were concerned with outward religious practices, but Jesus explains that true defilement comes from a person's inner thoughts and desires, not from failing to follow external rituals.

The Greek behind Matthew 15:19

• καρδία (kardia, "heart"): In Greek thought, the "heart" refers not just to emotions but to the center of a person's inner life—thoughts, intentions, and will. Jesus points to the heart as the source of both good and evil.
• διαλογισμοί (dialogismoi, "thoughts"): This word often means reasonings or deliberations, not just passing ideas. Here, it highlights that evil actions begin with inner reasoning or planning.
• ψευδομαρτυρία (pseudomartyria, "false witness"): This term means giving false testimony, especially in a legal sense. Jesus includes it to show that even dishonest speech is rooted in the heart.
• βλασφημίαι (blasphēmiai, "blasphemies"): This word refers to slander or speaking irreverently about God or sacred things. Jesus connects harmful speech about others and God to the inner life.

Why Matthew 15:19 matters

• Matthew 15:19 clarifies that moral and spiritual problems are not caused by external things or rituals but by what is already within a person.
• This verse challenges the idea that following religious traditions alone can make someone righteous, emphasizing the importance of inner character.
• The verse helps explain Jesus’ broader teaching in this chapter: true purity and impurity are matters of the heart, not just outward actions.
