Luke 20 – Who is the "Man" who planted the vineyard? What represents the vineyard? 2017

Luke 20:10
"And at the harvest time he sent a slave to the vine-growers, in order that they might give him some of the produce of the vineyard; but the vine-growers beat him and sent him away empty-handed.

This parable is also given in the Tanakh.

Isa 5:1-7 Let me sing now for my well-beloved A song of my beloved concerning His vineyard. My well-beloved had a vineyard on a fertile hill. 2And He dug it all around, removed its stones, And planted it with the choicest vine. And He built a tower in the middle of it, And hewed out a wine vat in it; Then He expected it to produce good grapes, But it produced only worthless ones. 3“And now, O inhabitants of Jerusalem and men of Judah, Judge between Me and My vineyard. 4“What more was there to do for My vineyard that I have not done in it? Why, when I expected it to produce good grapes did it produce worthless ones? 5“So now let Me tell you what I am going to do to My vineyard: I will remove its hedge and it will be consumed; I will break down its wall and it will become trampled ground. 6“And I will lay it waste; It will not be pruned or hoed, But briars and thorns will come up. I will also charge the clouds to rain no rain on it.” 7For the vineyard of the LORD of hosts is the house of Israel, And the men of Judah His delightful plant. Thus He looked for justice, but behold, bloodshed; For righteousness, but behold, a cry of distress.

Jer. 2:21 “Yet I planted you a choice vine, A completely faithful seed. How then have you turned yourself before Me Into the degenerate shoots of a foreign vine?

The symbolism in the parable is very easily discerned by itself, but the Tanakh references make it blatantly obvious. The "Man" who planted the vineyard is Elohim. The vineyard is the land of Israel. The vine-growers He rented it to are the sons of Israel. The slaves that are sent to the vine-growers are the prophets.
