Mark saith nothing of what Christ said to him. Luke, Luke 22:48, adds, that Christ said to him, Judas, betrayest thou the Son of man with a kiss? Whether Christ used this compellation of friend to Judas, to mind him what he formerly had been, and still ought to have been, or as a common compellation, (as we oft use it), is not much material. A kiss is the symbol of friendship and kindness, and therefore very improperly used by a traitor and professed enemy; yet so used by Joab to Amasa, 2 Samuel 20:9. That makes our Saviour ask him if he were not ashamed to betray the Son of man by a kiss. Judas, by calling him Master, master, acknowledged he had been once his disciple. By his kiss he pretended friendship to him, yet betrayed him. Oh the depth of desperate wickedness which is in the heart of man! Especially such as apostatize from a former profession; they are commonly the worst and most false enemies of Christ and his gospel.
