“Immediately aware

That power had gone forth

From him,

Jesus turned about

To the crowd.

He said,

‘Who touched

My clothes?’”

 

καὶ εὐθὺς ὁ Ἰησοῦς ἐπιγνοὺς ἐν ἑαυτῷ τὴν ἐξ αὐτοῦ δύναμιν ἐξελθοῦσαν, ἐπιστραφεὶς ἐν τῷ ὄχλῳ ἔλεγεν Τίς μου ἥψατο τῶν ἱματίων;

 

This question can be found in Luke, chapter 8:44-46, but not in Matthew.  Mark said that Jesus immediately realized in himself (καὶ εὐθὺς ὁ Ἰησοῦς ἐπιγνοὺς ἐν ἑαυτῷ) that power had gone forth from him (τὴν ἐξ αὐτοῦ δύναμιν ἐξελθοῦσαν).  Jesus then turned around to the crowd (ἐπιστραφεὶς ἐν τῷ ὄχλῳ).  He wanted to know who had touched his clothes (ἔλεγεν Τίς μου ἥψατο τῶν ἱματίων).  Both Jesus and the woman knew that something had happened.  Jesus, however, was unaware of whom he had healed.
