Matthew 15:9 (KJV)

What does Matthew 15:9 mean?

Matthew 15:9 says that people’s worship of God is empty when they present human commands as teachings to be followed. Jesus speaks these words to religious leaders who have challenged his disciples over a customary practice.

Jesus is quoting the prophet Isaiah, who spoke God’s words to people of his own time. The “me” in the quotation refers to God. After the mention of people whose hearts are far from God in verse 8, verse 9 turns to what those people teach.

The Greek behind Matthew 15:9

• “vain” — μάτην (matēn): This word carries the sense of “to no purpose” or “without result.” It describes worship that fails to achieve its purpose.
• “doctrines” — διδασκαλίας (didaskalias): The word means “teachings” or “things taught.” The phrase “teaching for doctrines” presents human commands as material people are expected to learn and follow.

Why Matthew 15:9 matters

• Jesus connects the quotation to a specific dispute about religious practice. In verses 1–2, the leaders question why his disciples eat without first washing their hands according to the tradition of the elders.
• Jesus also gives an example of a human tradition affecting a command from God. In verses 3–6, he challenges a practice involving a gift set aside for God that could be used to avoid helping one’s father or mother.
