What does John 13:21-22 Mean?

Contextual Meaning

The prospect of His imminent betrayal and death upset Jesus visibly (Gr. etarachthe, cf. John 11:33; John 12:27). Clearly the Twelve had not understood that one of them would betray Him (cf. Matthew 26:21-22; Mark 14:18-19; Luke 22:21-23). Judas had been a successful hypocrite. Jesus" solemn announcement now forced Judas to act quickly or to repent.
