Mark 9:19-21

New Catholic Bible

¹⁹ Jesus said to them in reply, “O unbelieving generation, how much longer shall I remain with you? How much longer must I put up with you? Bring the boy to me.” ²⁰ When they brought the boy to him, the spirit saw him and immediately threw the child into convulsions. He fell to the ground and rolled around, foaming at the mouth.

²¹ Jesus asked the father, “How long has the boy been in this condition?” “From childhood,” he replied.
