Mark 12:12
Then the chief priests, the teachers of the law and the elders looked for a way to arrest him because they knew he had spoken the parable against them. But they were afraid of the crowd; so they left him and went away — the Sanhedrin's response confirms that the parable was understood as Jesus intended: they knew he had spoken it against them. The comprehension that produces murderous intent (arrest) is balanced by the political constraint (fear of the crowd) that prevents it. They go away — temporarily. The parable has described exactly what they are about to do.
