Mark 9:27

Verse 27. This person, whom the apostles had forbidden to work miracles in the name of Christ, believed indeed in Christ, but did not follow him, on account of the great poverty of the apostles: he was not perfect, nor had he left all things to follow Christ. The apostles therefore concluded, that such a one was not worthy to work miracles in the name of their divine Master. But for this indiscretion, Christ rebukes them, saying, do not, and so forth Tirinus.
