Interestingly, in Gospel of Barnabas [which was considered as an authentic Gospel till 3rd CE], this parable is slightly different:
"Again spoke Jesus, saying: "I set before you an example. There was A HOUSEHOLDER WHO PLANTED A VINEYARD, and made a hedge for it in order that it should not be trampled down of beasts. And in the midst of it he built a press for the wine, and thereupon let it out to husbandman. Whereupon, when the time was come to collect the wine he sent his servants; whom when the husbandman saw, they stoned some and burned some, and others they ripped open with a knife. And this they did many times. Tell me, what will the lord of the vineyard do to the husbandmen"
Every one answered: "In evil wise will he make them to perish, and his vineyard will he give to other husbandman." Therefore said Jesus: "Know you not that the vineyard is the House of Israel, and the husbandman are the people of Judah and Jerusalem? Woe to you; for God is wroth with you, having ripped open so many prophets of God; so that at the time of Ahab ;there was not found one to bury the holy ones of God!" And when he had said this the chief priests wished to seize him, but they feared the common people, which magnified him. (Gospel of Barnabas, Chapter 46)
The concept found in Mathew 21:37 that 'I will send my son, and they will surely respect him" is a later adoption.Another interesting fact is that in this Gospel, Jesus us shown as who the 144000 real are. They are the total number of all prophets that have ever been sent by God on to this earth. (Chapter 17)
