This is unique to Matthew. Jesus said that the king addressed this man (καὶ λέγει αὐτῷ) without a wedding garment with a sarcastic greeting of “Friend (Ἑταῖρε).” How had he gotten into the wedding banquet without a wedding garment (ὧδε μὴ ἔχων ἔνδυμα γάμου)? The man without the wedding robe was speechless or silent (ὁ δὲ ἐφιμώθη). Then the king told his serving attendants (ότε ὁ βασιλεὺς εἶπεν τοῖς διακόνοις) to tie him up hand and foot (Δήσαντες αὐτοῦ πόδας καὶ χεῖρας) and throw him into the extreme darkness (ἐκβάλετε αὐτὸν εἰς τὸ σκότος τὸ ἐξώτερον). There would be weeping gnashing of teeth out there in this darkness (ἐκεῖ ἔσται ὁ κλαυθμὸς καὶ ὁ βρυγμὸς τῶν ὀδόντων), the traditional way of mourning. The moral of this parable was always wear the right clothes for every occasion.
This parable is unique to Matthew, as Jesus concluded this parable. The landowner replied to one of them (ὁ δὲ ἀποκριθεὶς ἑνὶ αὐτῶν) with a sarcastic greeting of companion or friend (εἶπεν Ἑταῖρε). He had done nothing wrong to them (οὐκ ἀδικῶ σε). They had agreed to the one denarius pay for a day’s work (οὐχὶ δηναρίου συνεφώνησάς μοι). They should just take their money and go (ἆρον τὸ σὸν καὶ ὕπαγε). If the landowner was generous that was not the problem of this day laborer. He could give to the last hired what he gave to the first hired (θέλω δὲ τούτῳ τῷ ἐσχάτῳ δοῦναι ὡς καὶ σοί). Was he not allowed (οὐκ ἔξεστίν μοι) to do whatever he wanted to do with his own belongings (ὃ θέλω ποιῆσαι ἐν τοῖς ἐμοῖς). Were they envious with an evil eye (ἢ ὁ ὀφθαλμός σου πονηρός ἐστιν) because he was generous (ὅτι ἐγὼ ἀγαθός εἰμι)? In fact, they did not mind generosity. They just wanted to know why none of that generosity came their way. That is the problem with generosity. The person who worked hard for a fair payment sometimes resents the generosity towards those who did not do as much work. Why was the hard worker for the whole day not compensated more generously than the one-hour worker? There are always two sides to every story.
