Matthew 17:14-20 New International Version (NIV)

Jesus Heals a Demon-Possessed Boy

¹⁴ When they came to the crowd, a man approached Jesus and knelt before him. ¹⁵ “Lord, have mercy on my son,” he said. “He has seizures and is suffering greatly. He often falls into the fire or into the water. ¹⁶ I brought him to your disciples, but they could not heal him.”

¹⁷ “You unbelieving and perverse generation,” Jesus replied, “how long shall I stay with you? How long shall I put up with you? Bring the boy here to me.” ¹⁸ Jesus rebuked the demon, and it came out of the boy, and he was healed at that moment.

¹⁹ Then the disciples came to Jesus in private and asked, “Why couldn’t we drive it out?”

²⁰ He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”

Matthew 15:10-20 New International Version (NIV)

¹⁰ Jesus called the crowd to him and said, “Listen and understand. ¹¹ What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them.”

¹² Then the disciples came to him and asked, “Do you know that the Pharisees were offended when they heard this?”

¹³ He replied, “Every plant that my heavenly Father has not planted will be pulled up by the roots. ¹⁴ Leave them; they are blind guides.^[a] If the blind lead the blind, both will fall into a pit.”

¹⁵ Peter said, “Explain the parable to us.”

¹⁶ “Are you still so dull?” Jesus asked them. ¹⁷ “Don’t you see that whatever enters the mouth goes into the stomach and then out of the body? ¹⁸ But the things that come out of a person’s mouth come from the heart, and these defile them. ¹⁹ For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander. ²⁰ These are what defile a person; but eating with unwashed hands does not defile them.”
