Matthew 17:19-26

19Then came the disciples to Jesus privately, and said, Why could not we cast him out? 20And Jesus said to them, Because of your unbelief: for verily I say to you, If ye have faith as a grain of mustard seed, ye shall say to this mountain, Move from here to yonder place; and it shall move; and nothing shall be impossible to you. 21However this kind goeth not out except by prayer and fasting.

22And while they abode in Galilee, Jesus said to them, The Son of man shall be betrayed into the hands of men: 23And they shall kill him, and the third day he shall be raised again. And they were exceedingly sorrowful.

24And when they had come to Capernaum, they that received tribute money came to Peter, and said, Doth not your master pay tribute?1 25He saith, Yes. And when he had come into the house, Jesus spoke to him first, saying, What thinkest thou, Simon? from whom do the kings of the earth take custom or tribute? from their own children, or from strangers? 26Peter saith to him, From strangers. Jesus saith to him, Then are the children free.
