According to the Jewish sages, all prophecy is about the time of the Messiah (IE: the first 70 years of the first century Anno Domini):
All the prophets prophesied only of the days of the Messiah.- Babylonian Talmud, Sanhedrin 99a
Jesus confirms this view:
[Luk 22:37 NKJV] (37) "For I say to you that this which is written must still be accomplished in Me: 'And He was numbered with the transgressors.' For the things concerning Me have an end."
[Luk 24:44 NKJV] (44) Then He said to them, "These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me."
[Mat 5:17-18 NKJV] (17) "Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. (18) "For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled.
[Luk 21:20-22 NASB] (20) "But when you see Jerusalem surrounded by armies, then recognize that her desolation is near. (21) "Then those who are in Judea must flee to the mountains, and those who are in the midst of the city must leave, and those who are in the country must not enter the city; (22) because these are days of vengeance, so that all things which are written will be fulfilled.
As does Paul:
[Col 2:16-17 NKJV] (16) So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, (17) which are a shadow of things to come, but the substance is of Christ.
So a proper use of the scriptures is to see in the NT scriptures the fulfillment of the OT:
[Mat 13:52 NKJV] (52) Then He said to them, "Therefore every scribe instructed concerning the kingdom of heaven is like a householder who brings out of his treasure things new and old."
The prophetic background of Jesus' parable is found in the treachery of Jezebel:
[1Ki 21:1-29 NLT] (1) Now there was a man named Naboth, from Jezreel, who owned a vineyard in Jezreel beside the palace of King Ahab of Samaria. (2) One day Ahab said to Naboth, "Since your vineyard is so convenient to my palace, I would like to buy it to use as a vegetable garden. I will give you a better vineyard in exchange, or if you prefer, I will pay you for it." (3) But Naboth replied, "The LORD forbid that I should give you the inheritance that was passed down by my ancestors." (4) So Ahab went home angry and sullen because of Naboth's answer. The king went to bed with his face to the wall and refused to eat! (5) "What's the matter?" his wife Jezebel asked him. "What's made you so upset that you're not eating?" (6) "I asked Naboth to sell me his vineyard or trade it, but he refused!" Ahab told her. (7) "Are you the king of Israel or not?" Jezebel demanded. "Get up and eat something, and don't worry about it. I'll get you Naboth's vineyard!" (8) So she wrote letters in Ahab's name, sealed them with his seal, and sent them to the elders and other leaders of the town where Naboth lived. (9) In her letters she commanded: "Call the citizens together for fasting and prayer, and give Naboth a place of honor. (10) And then seat two scoundrels across from him who will accuse him of cursing God and the king. Then take him out and stone him to death." (11) So the elders and other town leaders followed the instructions Jezebel had written in the letters. (12) They called for a fast and put Naboth at a prominent place before the people. (13) Then the two scoundrels came and sat down across from him. And they accused Naboth before all the people, saying, "He cursed God and the king." So he was dragged outside the town and stoned to death. (14) The town leaders then sent word to Jezebel, "Naboth has been stoned to death." (15) When Jezebel heard the news, she said to Ahab, "You know the vineyard Naboth wouldn't sell you? Well, you can have it now! He's dead!" (16) So Ahab immediately went down to the vineyard of Naboth to claim it. (17) But the LORD said to Elijah, (18) "Go down to meet King Ahab of Israel, who rules in Samaria. He will be at Naboth's vineyard in Jezreel, claiming it for himself. (19) Give him this message: 'This is what the LORD says: Wasn't it enough that you killed Naboth? Must you rob him, too? Because you have done this, dogs will lick your blood at the very place where they licked the blood of Naboth!'" (20) "So, my enemy, you have found me!" Ahab exclaimed to Elijah. "Yes," Elijah answered, "I have come because you have sold yourself to what is evil in the LORD's sight. (21) So now the LORD says, 'I will bring disaster on you and consume you. I will destroy every one of your male descendants, slave and free alike, anywhere in Israel! (22) I am going to destroy your family as I did the family of Jeroboam son of Nebat and the family of Baasha son of Ahijah, for you have made me very angry and have led Israel into sin.' (23) "And regarding Jezebel, the LORD says, 'Dogs will eat Jezebel's body at the plot of land in Jezreel.' (24) "The members of Ahab's family who die in the city will be eaten by dogs, and those who die in the field will be eaten by vultures." (25) (No one else so completely sold himself to what was evil in the LORD's sight as Ahab did under the influence of his wife Jezebel. (26) His worst outrage was worshiping idols just as the Amorites had done--the people whom the LORD had driven out from the land ahead of the Israelites.) (27) But when Ahab heard this message, he tore his clothing, dressed in burlap, and fasted. He even slept in burlap and went about in deep mourning. (28) Then another message from the LORD came to Elijah: (29) "Do you see how Ahab has humbled himself before me? Because he has done this, I will not do what I promised during his lifetime. It will happen to his sons; I will destroy his dynasty."
In fact, the entire message of the NT is that all of the functions of the Jewish theocracy died with Christ and were resurrected with all things being new, in Christ and his body aka "the kingdom of God".
The Answer, then, in my view:
In my view, the reason Jesus speaks of the tenant farmers "stealing the inheritance" is that he is associating their motives and actions to Ahab's and Jezebel's. That is, he is making a literary connection. The story is a parable about the hearts of the men, not their business arrangements.
In reality they were killed on judgment day in 70 AD during the Jewish war with Rome, per Ezekiel 34:
[Eze 34:17-24 NLT] (17) "And as for you, my flock, this is what the Sovereign LORD says to his people: I will judge between one animal of the flock and another, separating the sheep from the goats. (18) Isn't it enough for you to keep the best of the pastures for yourselves? Must you also trample down the rest? Isn't it enough for you to drink clear water for yourselves? Must you also muddy the rest with your feet? (19) Why must my flock eat what you have trampled down and drink water you have fouled? (20) "Therefore, this is what the Sovereign LORD says: I will surely judge between the fat sheep and the scrawny sheep. (21) For you fat sheep pushed and butted and crowded my sick and hungry flock until you scattered them to distant lands. (22) So I will rescue my flock, and they will no longer be abused. I will judge between one animal of the flock and another. (23) And I will set over them one shepherd, my servant David. He will feed them and be a shepherd to them. (24) And I, the LORD, will be their God, and my servant David will be a prince among my people. I, the LORD, have spoken!
[Mat 25:31-46 NLT] (31) "But when the Son of Man comes in his glory, and all the angels with him, then he will sit upon his glorious throne. (32) All the nations will be gathered in his presence, and he will separate the people as a shepherd separates the sheep from the goats. (33) He will place the sheep at his right hand and the goats at his left. (34) "Then the King will say to those on his right, 'Come, you who are blessed by my Father, inherit the Kingdom prepared for you from the creation of the world. (35) For I was hungry, and you fed me. I was thirsty, and you gave me a drink. I was a stranger, and you invited me into your home. (36) I was naked, and you gave me clothing. I was sick, and you cared for me. I was in prison, and you visited me.' (37) "Then these righteous ones will reply, 'Lord, when did we ever see you hungry and feed you? Or thirsty and give you something to drink? (38) Or a stranger and show you hospitality? Or naked and give you clothing? (39) When did we ever see you sick or in prison and visit you?' (40) "And the King will say, 'I tell you the truth, when you did it to one of the least of these my brothers and sisters, you were doing it to me!' (41) "Then the King will turn to those on the left and say, 'Away with you, you cursed ones, into the eternal fire prepared for the devil and his demons. (42) For I was hungry, and you didn't feed me. I was thirsty, and you didn't give me a drink. (43) I was a stranger, and you didn't invite me into your home. I was naked, and you didn't give me clothing. I was sick and in prison, and you didn't visit me.' (44) "Then they will reply, 'Lord, when did we ever see you hungry or thirsty or a stranger or naked or sick or in prison, and not help you?' (45) "And he will answer, 'I tell you the truth, when you refused to help the least of these my brothers and sisters, you were refusing to help me.' (46) "And they will go away into eternal punishment, but the righteous will go into eternal life."
This all took place in 70 AD. The sheep were the 144000 elect, remnant Jews who were caught up to be with the LORD in the air (and not missed because of the war) and accompanied Jesus the Messiah when he destroyed Jerusalem. The goats and former tenants were, as they surmised, the unregenerate, apostate Jewish leadership of the temple based Jerusalem theocracy that was replaced by the kingdom of God aka Christ and his body.
[Jhn 10:6-16 NLT] (6) Those who heard Jesus use this illustration didn't understand what he meant, (7) so he explained it to them: "I tell you the truth, I am the gate for the sheep. (8) All who came before me were thieves and robbers. But the true sheep did not listen to them. (9) Yes, I am the gate. Those who come in through me will be saved. They will come and go freely and will find good pastures. (10) The thief's purpose is to steal and kill and destroy. My purpose is to give them a rich and satisfying life. (11) "I am the good shepherd. The good shepherd sacrifices his life for the sheep. (12) A hired hand will run when he sees a wolf coming. He will abandon the sheep because they don't belong to him and he isn't their shepherd. And so the wolf attacks them and scatters the flock. (13) The hired hand runs away because he's working only for the money and doesn't really care about the sheep. (14) "I am the good shepherd; I know my own sheep, and they know me, (15) just as my Father knows me and I know the Father. So I sacrifice my life for the sheep. (16) I have other sheep, too, that are not in this sheepfold. I must bring them also. They will listen to my voice, and there will be one flock with one shepherd.
