Matthew 17:19

Then, the disciples, coming near, to Jesus, privately, said - Wherefore could, we, not cast it out?

And when he was alone they who were about him with the twelve questioned him as to the parables;

And, when he had gone into a house, his disciples, privately, were questioning him - Why, were, we, not able to cast it out?
