Malchus (/ˈmælkəs/; Koinē Greek: Μάλχος, romanized: Málkhos, pronounced [ˈmal.kʰos]) was the servant of the Jewish High Priest Caiaphas who participated in the arrest of Jesus as written in the four gospels.
The relevant passages in the Gospels of John and Luke, KJV, read: 10 Then Simon Peter having a sword drew it, and smote the high priest's servant, and cut off his right ear.
4th century church father Jerome cites a post-resurrection appearance of Jesus to Malchus, quoting a passage from the lost "gospel according to the Hebrews."
In this depiction, Jesus heals Malchus' wounded ear, leaving the latter to stay behind sitting dumbfounded in a state of disbelief, suggesting a possible conversion to Christianity.
Isak Dinesen in The Deluge at Norderney (the first of Seven Gothic Tales) relates a story about Simon Peter wherein he uses the memory of cutting off Malchus' ear "to control his temper".
