Matthew 15:17-19

Revised Standard Version Catholic Edition

¹⁷ Do you not see that whatever goes into the mouth passes into the stomach, and so passes on?^{[a] 18} But what comes out of the mouth proceeds from the heart, and this defiles a man. ¹⁹ For out of the heart come evil thoughts, murder, adultery, fornication, theft, false witness, slander.
