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.
Context
18 and wherever it seizes him, it throws him down; and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, and they weren’t able.”
19 He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”
20 They brought him to him, and when he saw him, immediately the spirit convulsed him and he fell on the ground, wallowing and foaming at the mouth.
