Mark 9:14-19 King James Version (KJV)
14 And when he came to his disciples, he saw a great multitude about them, and the scribes questioning with them.
15 And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him.
16 And he asked the scribes, What question ye with them?
17 And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit;
18 And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
19 He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.
Mark 9:14-19 Amplified Bible, Classic Edition (AMPC)
14 And when they came to the [nine] disciples, they saw a great crowd around them and scribes questioning and disputing with them.
15 And immediately all the crowd, when they saw Jesus [[a]returning from the holy mount, His face and person yet glistening], they were greatly amazed and ran up to Him [and] greeted Him.
16 And He asked them, About what are you questioning and discussing with them?
17 And one of the throng replied to Him, Teacher, I brought my son to You, for he has a dumb spirit.
18 And wherever it lays hold of him [so as to make him its own], it dashes him down and convulses him, and he foams [at the mouth] and grinds his teeth, and he [[b]falls into a motionless stupor and] is wasting away. And I asked Your disciples to drive it out, and they were not able [to do it].
19 And He answered them, O unbelieving generation [without any faith]! How long [c]shall I [have to do] with you? How long am I to bear with you? Bring him to Me.
