Luke 22:48

But Jesus said unto him, Judas, betrayest thou the Son of man with a kiss?

There is no vocabulary sufficiently extensive to describe the dastardly act of Judas Iscariot. The rationalistic devices of some who would extenuate his treachery, the "explanations" of those who exhibit some diabolical affinity with the traitor himself, together with all the brilliant and clever imaginations set to work out some justification of the traitor's deed - all of these have utterly failed to redeem Judas in the thinking of upright men from the shame of this betrayal.

Son of man ... By such a word, Jesus reminded Judas that it was no mere human teacher that he was betraying. The divine Messiah was the one whom he betrayed with a kiss; and such an act was so unbelievable that it called forth the Saviour's exclamation here. There is a further glimpse of the Lord's omniscience here. Before Judas profaned the Lord's cheek with his kiss, Jesus exposed his intention.
