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.

But there was a servant named Malchus. He mentions the name of the servant to signify the mystery. For Malchus is the same as "king." But as the servant of the High Priest he signifies the Jewish people, which was formerly a kingly and free power, but afterwards became subject to the Priesthood, which burdened it with its traditions and ceremonies, and also preyed upon it. See Matt. xxiii. Now this Prayer of Manasseh , when S. Peter and the Apostles preached the Gospel, lost his right ear on account of his unbelief and hatred of Christ: that Isaiah , he became deaf to the Gospel, and to those things which were necessary to salvation, till the Lord converted him, and healed his ear. So S. Cyril (in loc.), S. Ambrose on Luke 22:5-51., and S. Jerome on Matthew 26:51-52 S. Ambrose adds that S. Peter wished to imitate the zeal of Phinehas, who slew a prince of Israel who committed fornication with the daughters of Moab: and thus obtained the High Priesthood (Num. xxv.) The love therefore of S. Peter, and his zeal for Christ, lessened his fault. And yet he sinned in drawing his sword without consulting Christ, more especially when he had heard just before from His own lips, that He was going of His own accord to His Passion and Death.
