Matthew 15:17-19

Amplified Bible

¹⁷ Do you not understand that whatever goes into the mouth passes into the stomach, and is eliminated? ¹⁸ But whatever [word] comes out of the mouth comes from the heart, and this is what defiles and dishonors the man. ¹⁹ For out of the heart come evil thoughts and plans, murders, adulteries, sexual immoralities, thefts, false testimonies, slanders (verbal abuse, irreverent speech, blaspheming).
