Peter, who is Jesus's brother.
After Peter cut off the ear of the high priest's servant, Jesus rebuked him, saying, "Put your sword back in its place, for all who draw the sword will die by the sword." He then healed the servant's ear, emphasizing that his mission was not to resort to violence. Jesus highlighted the importance of fulfilling the scriptures and God's plan rather than engaging in conflict.
In the Garden of Gethsemane, Peter committed a violent act by cutting off the ear of Malchus, a servant of the high priest. This incident is recorded in the Bible in the Gospel of John (John 18:10). Peter's impulsive actions were in response to the arrest of Jesus by the Roman soldiers and temple guards.
The priests grow beards because they have the feeling of thinking if hair is cut it brings you bad things so they don't cut it :D
John 18:10 - Then Simon Peter, having a sword, drew it and struck the high priest's servant, and cut off his right ear. The servant's name was Malchus. [NKJV]
No roman soldier actually had his ear cut off. The incident occurred as soldiers came to arrest Jesus, and with them were some officials from the chief priests and Pharisees. The gospels of Matthew and Luke do not record the name of the disciple who cut off the ear of a servant of the high priest. John 18:10 records that it was Simon Peter, and that the servant's name was Malchus.
