Matthew 15:17-19

New Revised Standard Version Catholic Edition

¹⁷ Do you not see that whatever goes into the mouth enters the stomach, and goes out into the sewer? ¹⁸ But what comes out of the mouth proceeds from the heart, and this is what defiles. ¹⁹ For out of the heart come evil intentions, murder, adultery, fornication, theft, false witness, slander.
