“After a long time,
Of those slaves
He settled accounts
μετὰ δὲ πολὺν χρόνον ἔρχεται ὁ κύριος τῶν δούλων ἐκείνων καὶ συναίρει λόγον μετ’ αὐτῶν.
This parable is unique to Matthew, but there is an equivalent in Luke, chapter 19:15, where the nobleman wanted to settle his accounts after being away for a time. Jesus said that after a long time (μετὰ δὲ πολὺν χρόνον), the master or lord of these slaves came back (ἔρχεται ὁ κύριος τῶν δούλων ἐκείνων). He then wanted to settle his accounts with his slaves (καὶ συναίρει λόγον μετ’ αὐτῶν).
