Betrayed.

Then Satan entered Judas, surnamed Iscariot, who was numbered among the twelve. So he went his way and conferred with the chief priests and captains, how he might betray Him to them. 
And they were glad, and agreed to give him money. So he promised and sought opportunity to betray Him to them in the absence of the multitude. (Luke 22:3-6)

And immediately, while he was still speaking, Judas came, one of the twelve, and with him a crowd with swords and clubs, from the chief priests and the scribes and the elders. 

Now the betrayer had given them a sign, saying, “The one I shall kiss is the man; seize him and lead him away under guard.” 

And when he came, he went up to him at once, and said, “Master!” 

And he kissed him. And they laid hands on him and seized him. (Mark 14:43-46)
