38 ΒΆ And Iohn answered him, saying, Master, we saw one casting out deuils in thy Name, and he followeth not vs, and we forbade him, because he followeth not vs.
39 But Iesus said, Forbid him not, for there is no man, which shall doe a miracle in my Name, that can lightly speake euill of me.
40 For he that is not against vs, is on our part.
41 For whosoeuer shall giue you a cup of water to drinke in my Name, because yee belong to Christ: Uerily I say vnto you, he shall not lose his reward.
Mk 9:38-41
