To his disciples.
Can come out
Only through prayer.’”
καὶ εἶπεν αὐτοῖς Τοῦτο τὸ γένος ἐν οὐδενὶ δύναται ἐξελθεῖν εἰ μὴ ἐν προσευχῇ.
Mark added the need for prayer. There is no emphasis on faith as in Matthew, chapter 17:20, where Jesus talked about faith and the mustard seed. Here the emphasis is on prayer. Mark indicated that Jesus said to his disciples (καὶ εἶπεν αὐτοῖς) that this kind of evil spirit could only be expelled (Τοῦτο τὸ γένος ἐν οὐδενὶ δύναται ἐξελθεῖν) through prayer (εἰ μὴ ἐν προσευχῇ). Prayer might imply faith, but it is not explicit here.
