“But one of those
Who stood nearby
Drew his sword.
He struck
The slave
Of the high priest.
He cut off his ear.”
εἷς δέ τις τῶν παρεστηκότων σπασάμενος τὴν μάχαιραν ἔπαισεν τὸν δοῦλον τοῦ ἀρχιερέως καὶ ἀφεῖλεν αὐτοῦ τὸ ὠτάριον.
This is similar to Matthew, chapter 26:51. In Luke, chapter 22:49-51, there was a little discussion before the cutting off of the ear. Then Jesus healed the ear that was hurt. John, chapter 18:10-11, explicitly named Peter, not one of those with Jesus, as the one who cut off the ear of the high priest’s slave. In fact, the slave has the name of Malchus. Mark said that one of these unnamed apostles was standing nearby Jesus (εἷς δέ τις τῶν παρεστηκότων). He then drew his sword (σπασάμενος τὴν μάχαιραν) and struck a slave of the high priest (ἔπαισεν τὸν δοῦλον τοῦ ἀρχιερέως). He cut his ear off (καὶ ἀφεῖλεν αὐτοῦ τὸ ὠτάριον). Obviously, this could have started a major battle, also indicating that these apostles were armed and ready to do battle, if necessary.
