Note 1 at Mt 26:6: Matthew's and Mark's placement of this event in their Gospels differs greatly with where John placed this anointing of Jesus. John made it very clear, however, that this event took place the day before Jesus' triumphant entry into Jerusalem (Joh 12:12); therefore, John was the writer who was setting forth the proper sequence of events.

Matthew and Mark both list Mary anointing Jesus and then Judas' reaction in association with his betrayal of Jesus (Mt 26:1-16 and Mr 14:1-11). This might possibly have been done to emphasize a connection between Judas' disdain for this "waste" (Mt 26:8) and his betrayal of the Lord. Judas might also have been embarrassed by Jesus' rebuke (Mr 14:6-9) and therefore used his betrayal to "get even" with Jesus. Chronological order was not the main concern of Matthew's and Mark's Gospels.
