Mark 9:38-41

Revised Standard Version

Another Exorcist

³⁸ John said to him, “Teacher, we saw a man casting out demons in your name,^[a] and we forbade him, because he was not following us.” ³⁹ But Jesus said, “Do not forbid him; for no one who does a mighty work in my name will be able soon after to speak evil of me. ⁴⁰ For he that is not against us is for us. ⁴¹ For truly, I say to you, whoever gives you a cup of water to drink because you bear the name of Christ, will by no means lose his reward.
