8 “Blessed are the pure in heart, for they shall see God

Matthew 15:11-12, 17-20 ESV
11 it is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.” 12 Then the disciples came and said to him, “Do you know that the Pharisees were offended when they heard this saying?”
17 Do you not see that whatever goes into the mouth passes into the stomach and is expelled? 18 But what comes out of the mouth proceeds from the heart, and this defiles a person. 19 For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. 20 These are what defile a person. But to eat with unwashed hands does not defile anyone.”
