Salute Herodion my kinsman,.... According to the flesh, being of the same nation, a Jew; or of the same tribe, the tribe of Benjamin; or of the same family, and nearly allied in blood to him: though the name is of Attic, or Parthic original, and seems to be a derivative of Herod; this man is reckoned among the seventy disciples, and said to be bishop of Tarsus: See Gill on "Lu 10:1".
Greet them that be of the household of Narcissus, which are in the Lord; some have thought, that this Narcissus is the same man that Suetonius and other writers speak of , who was secretary to Claudius Caesar; a very great favourite of his, who amassed a great deal of wealth under him, and was raised to great honour and dignity by him: he himself is not saluted, either because he was not at home, which might be the case, if, as Ambrose, or rather Hilary the deacon on the text says, he was a presbyter and abroad, performing his office in foreign parts; or because he was dead, or rather not a believer: if he was the same with Claudius's favourite, he was dead before this time, being miserably put to death by Agrippina , the wife of Claudius; and seems to have died a wicked man, and justly punished for his being the cause of the destruction of others, through his calumnies: nor are all of his household saluted, not being all converted persons; it being frequently the method of divine grace to take some of a family, and not all, and bring them to Zion; only those that were "in the Lord", on his heart, and in his hands, secretly represented by him, and united to him, and who were openly in him, being called by his grace, and brought to believe in him, and live upon him.
