“But they made light of it.
They went away,
One to his own farm,
Another to his trading business.”
οἱ δὲ ἀμελήσαντες ἀπῆλθον, ὃς μὲν εἰς τὸν ἴδιον ἀγρόν, ὃς δὲ ἐπὶ τὴν ἐμπορίαν αὐτοῦ·
This refusal has more details in Luke, chapter 14:18-20. Jesus said that they made up specific excuses on why they could not go to the wedding banquet. But Matthew said that they made light of them, disregarded or disrespected (οἱ δὲ ἀμελήσαντες) this second invitation. They simply went on with their daily life, they went (ἀπῆλθον) one to his own farm or field (ὃς μὲν εἰς τὸν ἴδιον ἀγρόν), and another to his trading business (ὃς δὲ ἐπὶ τὴν ἐμπορίαν αὐτοῦ). They were too busy to go to a wedding feast.
