9 And his disciples asked him, saying, Why then say the Scribes that Elias must first come?
10 And Jesus answered and said unto them, Elias truly shall first come, and restore all things, as the prophets have written.
11 And again I say unto you that Elias has come already, concerning whom it is written, Behold, I will send my messenger, and he shall prepare the way before me; and they knew him not, and have done unto him, whatsoever they listed.
12 Likewise shall also the Son of Man suffer of them.
13 But I say unto you, Who is Elias? Behold, this is Elias, whom I send to prepare the way before me.
14 Then the disciples understood that he spake unto them of John the Baptist, and also of another who should come and restore all things, as it is written by the prophets.
15 And when they were come to the multitude, there came to him a man kneeling down to him, and saying, Lord, have mercy on my son; for he is lunatic, and sore vexed; for ofttimes he falleth into the fire, and oft into the water.
16 And I brought him to thy disciples, and they could not cure him.
17 Then Jesus answered and said, O faithless and perverse generation! how long shall I be with you? How long shall I suffer you? Bring him hither to me.
18 And Jesus rebuked the devil, and he departed out of him; and the child was cured from that very hour.
19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
