John 18:10

All the Gospels record this incident, but John is the only one that names Peter and Malchus. The mention of their names makes the story more concrete. John was an eyewitness of Jesus’ sufferings, so it is not unusual that He would mention these names. The small sword (Gr. machaira) that Peter used was probably little more than a dagger. His action was foolish, but it illustrates his courage and commitment to Jesus (cf. John 13:37).
