What are you here
Then the others came.
They laid hands
They seized him.”
ὁ δὲ Ἰησοῦς εἶπεν αὐτῷ Ἑταῖρε, ἐφ’ ὃ πάρει. τότε προσελθόντες ἐπέβαλον τὰς χεῖρας ἐπὶ τὸν Ἰησοῦν καὶ ἐκράτησαν αὐτόν.
This is similar to Mark, chapter 14:46, but Jesus did not respond to Judas there. In Luke, chapter 22:48, Jesus reprimanded Judas for betraying him with a kiss, while in John, chapter 18, there was no Judas kiss, instead there was a dialogue of Jesus with those who came to get him. Only Matthew remarked that Jesus called Judas “Friend!” (ὁ δὲ Ἰησοῦς εἶπεν αὐτῷ Ἑταῖρε) sarcastically. Jesus wanted to know what Judas was there to do (ἐφ’ ὃ πάρει). What did he want? The answer came quickly, as others came forward and put their hands upon or grabbed Jesus (τότε προσελθόντες ἐπέβαλον τὰς χεῖρας ἐπὶ τὸν Ἰησοῦν). They seized or arrested him (καὶ ἐκράτησαν αὐτόν).
