This parable story about the dishonest household manager or steward can only be found in Luke, not in any of the other gospel stories. Luke indicated that Jesus said that this fired household manager came up with a plan. He decided what to do (ἔγνων τί ποιήσω). After he was dismissed as a house manager (ἵνα ὅταν μετασταθῶ ἐκ τῆς οἰκονομίας), he wanted people to welcome him into their homes (δέξωνταί με εἰς τοὺς οἴκους ἑαυτῶν). It is always a good idea to make plans before you leave a job. This dishonest house manager was no exception. He had a plan to survive. Do you have any plans in case you lose your job?
All three synoptic gospels. Mark, chapter 5;14, and Luke, chapter 8:34, and Matthew here, have the herdsmen of these pigs tell everybody in the area what happened, with slight nuances in each story. The shepherds of these herds of pigs ran off (οἱ δὲ βόσκοντες ἔφυγον) when they saw what had happened to their flocks. They went into the town (καὶ ἀπελθόντες εἰς τὴν πόλιν), probably Gadara. Then they told the whole story about what had happened to the demoniacs (ἀπήγγειλαν πάντα καὶ τὰ τῶν δαιμονιζομένων) and their herd of pigs. They were without a job.
