Hello,
I though that it would be good to respond much earlier, but I have a 12 hr or so lag because of the need to sleep to which overpowers any of the thoughts that I might have had.
The beginning of Israel, can only be linked with the Birth of Isaac, out of which the seed of Israel developed through the selection of Jacob initially and then the subsequent sons born to Jacob.
Initially, the first husbandman of God was Abraham at the very start and is found in Genesis 18:19: - 19 For I have known him, in order that he may command/teach his children and his household after him, that they keep the way of the Lord, to do righteousness and justice, that the Lord may bring to Abraham what He has spoken to him."
For some 635 years the heads of the households of the tribes of Israel acted as the "Priests" over their household and, at Mt. Sinai, God entered into a Covenant with Israel to be a Kingdom of Priests and a Holy Nation, and His Possession among the nations, but in under forty days, leaders of the tribes rebelled against God and sinned wanting to have god's similar to what they had experienced in Egypt over them because of the silence of Moses while he was up on the Mountain with God.
Moses intercession on behalf of the tribes of Israel, saved Israel from God's desire to destroy the nation of Israel, and because princes of the tribes of Israel had rebelled against God, God then set over Israel only one tribe to be the priests for the twelve tribes
Sadly, the understanding of God, passed down from Abraham to Gethro a descendant of Abraham's second family through Keturah, who was a friend of God, and then to Moses was slowly lost over the next 1400 or so years and the understanding of being in relationship with their God, lost out to the prescriptive method of establishing their relationship with God on a yearly basis when they would offer up their sin offering, but sadly they lost all understanding of what it meant to have a heart after God.
In Daniel 9:25, God gave Israel 490 years to stop their transgressions against God before the end of the second age of their existance, but even the Priestly orders continued in their idolatrous practices such that the Second Commandment, found in Exodus 20:4-6, kicked in and the visitation of the iniquities of the fathers of the first two ages of Israel began because Israel would not repent, nor did the Priestly leaders of the nation lead them into repentance for their idolatrous behaviour.
Jesus came, around 30 years later, teaching that the nation of Israel needed to repent of their sins and that they needed to sin no more. The priest knew that this was indeed the message that they themselves should have been preaching, and that they were the leaders of a wicked nation who should have been teaching the nation to repent of their sins. They also knew from Daniel 11, that the people who rejected the covenant would be complicit with the Little Horn's agent that was coming to destroy the Nation. They also knew that their Messiah was to come, but because Christ coming was unsettling for them, they chose to reject the cornerstone, that truth that would come down out of heaven during the time of the many nations having dominion over Babylon and grind into dust those nations that rejected that truth such that it would be blown away before the end of the ages of the Age.
The parable of the Wicked Tenants is contrasted by the Parable of a Man who had Planted a Fig Tree who continued to look for fruit from the tree for three seasons, and when he had found no fruit, he asked the husbandman of his garden to destroy the fig tree, but the husbandman interceded on behalf of the Fig Tree and asked for another season to see if the Fig Tree would bear fruit by the end of that season so that the Fig Tree would live.
God has not yet rejected the nation of Israel and as Paul tells us in Romans 11:25-26 all of Israel will be saved after the judgement of the wicked heavenly hosts in the heavens and the kings of the earth on the earth at Armageddon when the trampling of the Sanctuary of God by the Heathen Gentiles will end after the passing of 2,300 years.
God has rejected the Priesthood of Jesus' day but He intends to gather all of Israel to Himself and plant them in fertile soil and to teach them about the truth found in the foundational Rock that is to come down out of heaven in our near future. God will train up Israel Himself to become a Kingdom of Priests and a Holy Nation and His possession among the nations once more.
As has been suggested above, the present day "priest" need to consider their position in Christ and the teaching that they are giving to verify that it is in accordance with the understanding of God. God is looking for a people who understand the meaning of God's Justice in providing for the widows and orphans, the hungry and the naked and those who have had a heavy burden placed onto them by wrong understanding, and who will keep God's Sabbath Day for Mankind Holy.
What can we learn from the Parable of the wicked tenants? That we need to know the heart of God in all things and be prepared to wear that on the outside so that all will see what it means to be a disciple of Christ, even if it is costly to do, even at the cost of our own life.
Shalom
