This parable was against the Jewish leaders (Mk 12:12-12:12)

“When they realized

That he had told

This parable

Against them,

They wanted

To arrest Jesus.

But they feared

The crowd.

Thus,

They left him.

They went away.”

 

Καὶ ἐζήτουν αὐτὸν κρατῆσαι, καὶ ἐφοβήθησαν τὸν ὄχλον· ἔγνωσαν γὰρ ὅτι πρὸς αὐτοὺς τὴν παραβολὴν εἶπεν. καὶ ἀφέντες αὐτὸν ἀπῆλθον.

 

This was an admission by Jewish religious leaders, the chief priests and the Pharisees, as named in Matthew chapter 21:45-46, and Luke, chapter 20:19, but not here, about the deteriorating situation.  Mark said that the unnamed “they” were trying or seeking to get a hold of or arrest Jesus (Καὶ ἐζήτουν αὐτὸν κρατῆσαι).  However, they were afraid of the crowd (καὶ ἐφοβήθησαν τὸν ὄχλον).  They realized or knew that Jesus had told this parable against them (ἔγνωσαν γὰρ ὅτι πρὸς αὐτοὺς τὴν παραβολὴν εἶπεν), the wicked evil tenants of the vineyard.  The landowner was God the Father.  The slaves were the Israelite prophets, while Jesus was the son of the Father.  Thus, they left him (καὶ ἀφέντες αὐτὸν) and went away (ἀπῆλθον).  This will not turn out well.
