[Jesus] went on to tell the people this parable: “A man planted a vineyard, rented it to some farmers and went away for a long time. At harvest time he sent a servant to the tenants so they would give him some of the fruit of the vineyard. But the tenants beat him and sent him away empty-handed.
“He sent another servant, but that one also they beat and treated shamefully and sent away empty-handed.
“He sent still a third, and they wounded him and threw him out.
“Then the owner of the vineyard said, ‘What shall I do? I will send my son, whom I love; perhaps they will respect him.’
“But when the tenants saw him, they talked the matter over. ‘This is the heir,’ they said. ‘Let’s kill him, and the inheritance will be ours.’ So they threw him out of the vineyard and killed him.
“What then will the owner of the vineyard do to them? He will come and kill those tenants and give the vineyard to others.”
When the people heard this, they said, “May this never be!”
Jesus looked directly at them and asked, “Then what is the meaning of [this scripture]: ‘The stone the builders rejected has become the cornerstone’?
“Everyone who falls on that stone will be broken to pieces, but he on whom it falls will be crushed.”
The teachers of the law and the chief priests looked for a way to arrest him immediately, because they knew he had spoken this parable against them. But they were afraid of the people.
Keeping a close watch on him, they sent spies, who pretended to be honest. They hoped to catch Jesus in something he said so that they might hand him over to the power and authority of the governor.
Actually there is quite a bit here to feast on. But the main point of the parable should be obvious, that the people in power will be booted out since they are so corrupt, lying, deceiving, thieving murders.
We also see some of how God works. God takes the things people despise and exalts them, and vice versa.
Spies who pretended to be honest, hoping to catch Jesus in something they considered illegal, hm, sound familiar? Yes, sounds like bribed informants and undercover agents themselves! So don't deceive yourselves into thinking you’re stopping moral decay by "doing your job." READ THE VERY BIBLE YOU TAKE TO CHURCH!
