“Now the betrayer

Had given them

A sign.

He said.

‘The one I will kiss

Is the man.

Seize him!

Lead him away

Under guard!’”

 

δεδώκει δὲ ὁ παραδιδοὺς αὐτὸν σύσσημον αὐτοῖς λέγων Ὃν ἂν φιλήσω αὐτός ἐστιν· κρατήσατε αὐτὸν καὶ ἀπάγετε ἀσφαλῶς.

 

This is almost word for word in Matthew, chapter 26:48.  In Luke, chapter 22:47, there is an abbreviated version of only Judas kissing Jesus.  In John, chapter 18:2-9, there is long dialogue of Jesus with the crowd, with no Judas kiss at all.  It is interesting to note that John left this out in his otherwise well detailed description.  Mark said that this betrayer or deliverer of Jesus, Judas, had given the crowd a sign (δεδώκει δὲ ὁ παραδιδοὺς αὐτὸν σύσσημον αὐτοῖς).  Judas had told them that the one that he kissed (λέγων Ὃν ἂν φιλήσω) would be the man to seize or hold (αὐτός ἐστιν·κρατήσατε αὐτὸν).  They were to lead him away securely under guard (καὶ ἀπάγετε ἀσφαλῶς).  Judas had this all set up, so that there would be no mistaken identity, as regards Jesus.
