The Betrayal: "He...lifted up his heel against me."

26:3  Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas,
26:4  And consulted that they might take Jesus by subtilty, and kill him.

26:14  Then one of the twelve, called Judas Iscariot, went unto the chief priests,
26:15  And said unto them, What will ye give me, and I will deliver him unto you? And they covenanted with him for thirty pieces of silver.
26:16  And from that time he sought opportunity to betray him.

As a group, the chief priests, and the scribes, and the elders of the people became enemies of Jesus as indicated above by their their consultation to take  him and kill him.

Judas, an apostle of Jesus, betrayed him by offering to aid them.

This betrayal is the trespass of which Jesus spoke, " ... He that eateth bread with me hath lifted up his heel against me."  John 13:18

Jesus taught how to respond to a trespass. He said, "Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone; if he shall hear thee, thou hast gained thy brother."  Matthew 18:15

He gave an example of this teaching at the foot washing.

See, "Judas Iscariot: Saved and Servant of Jesus."
