Matthew 17:14 YLT

¹²  and I say to you -- Elijah did already come, and they did not know him, but did with him whatever they would, so also the Son of Man is about to suffer by them.'

¹³  Then understood the disciples that concerning John the Baptist he spake to them.

¹⁴  And when they came unto the multitude, there came to him a man, kneeling down to him,

¹⁵  and saying, 'Sir, deal kindly with my son, for he is lunatic, and doth suffer miserably, for often he doth fall into the fire, and often into the water,

¹⁶  and I brought him near to thy disciples, and they were not able to heal him.'
