Matthew 17:13-23

13 Then the disciples understood, that he had spoken to them of John the Baptist.

14 And when he was come to the multitude, there came to him a man falling down on his knees before him saying:

15 Lord, have pity on my son, for he is a lunatic, and suffereth much: for he falleth often into the fire, and often into the water.

16 (17-15) And I brought him to thy disciples, and they could not cure him.

17 (17-16) Then Jesus answered and said: O unbelieving and perverse generation, how long shall I be with you? How long shall I suffer you? Bring him hither to me.

18 (17-17) And Jesus rebuked him, and the devil went out of him, and the child was cured from that hour.

19 (17-18) Then came the disciples to Jesus secretly, and said: Why could not we cast him out?

20 (17-19) Jesus said to them: Because of your unbelief. For, amen I say to you, if you have faith as a grain of mustard seed, you shall say to this mountain: Remove from hence hither, and it shall remove: and nothing shall be impossible to you.

21 (17-20) But this kind is not cast out but by prayer and fasting.

22 (17-21) And when they abode together in Galilee, Jesus said to them: The Son of man shall be betrayed into the hands of men:

23 (17-22) And they shall kill him, and the third day he shall rise again. And they were troubled exceedingly.
