So many signs
In their presence,
They still did not believe
Τοσαῦτα δὲ αὐτοῦ σημεῖα πεποιηκότος ἔμπροσθεν αὐτῶν οὐκ ἐπίστευον εἰς αὐτόν,
Then John uniquely indicated that although Jesus had performed (πεποιηκότος) so many of his signs (Τοσαῦτα δὲ αὐτοῦ σημεῖα) in their presence (ἔμπροσθεν αὐτῶν), many of the Jerusalem Jews still did not believe in him (οὐκ ἐπίστευον εἰς αὐτόν). John surveyed the situation. Jesus had done a lot of miracles or signs in or near Jerusalem, but many of these people still did not believe in Jesus. What sign or miracle would you want to believe in Jesus?
