Haweis(i)
17 And one of the people addressing him, said, Master, I have brought my son to thee, who hath a dumb spirit;
18 and wherever he seizeth him, he throws him into strong convulsions: and he foams at the mouth, and grinds his teeth, and pines away. And I spoke to thy disciples, that they should cast him out; and they were unable.
19 Then addressing him, he said, O faithless generation, how long shall I be with you? how long shall I bear with you? bring him to me.
20 And they brought him unto him. And seeing him, instantly the spirit threw him into convulsions; and falling to the ground, he rolled about, foaming at the mouth.
21 And he asked his father, For how long a time hath this been the case with him? And he replied, From his infancy.
22 And often it hath cast him into the fire, and into water, to destroy him: but if thou art able, have compassion upon us, and help us.
23 Then said Jesus unto him, This [is the point]: if thou canst believe, all things are possible to him that believeth.
