Mark 7:18-23 (Living Standard Bible)
And He said to them, “Are you lacking understanding in this way as well? Do you not perceive that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and goes to the sewer?” (Thus He declared all foods clean.) And He was saying, “That which proceeds out of the man, that is what defiles the man. For from within, out of the heart of men, proceed the evil thoughts, sexual immoralities, thefts, murders, adulteries, coveting, wickedness, deceit, sensuality, envy, slander, pride, and foolishness. All these evil things proceed from within and defile the man.”
