Matthew 17:15–20

15 said, “Lord, have mercy on my son, for he is ban epileptic and he suffers terribly. For often he falls into the fire, and often into the water. 16 And I brought him to your disciples, and cthey could not heal him.” 17 And Jesus answered, “O faithless and dtwisted generation, how long am I to be with you? eHow long am I to bear with you? Bring him here to me.” 18 And Jesus frebuked the demon,2 and it3 came out of him, and gthe boy was healed instantly.4 19 Then the disciples came to Jesus privately and said, “Why could we not cast it out?” 20 He said to them, h“Because of your little faith. For itruly, I say to you, jif you have faith like a grain of mustard seed, kyou will say to this mountain, ‘Move from here to there,’ and it will move, and lnothing will be impossible for you.”5
