Specifically, vs. 19-22. They have shed the innocent blood of their own Messiah/Savior Prov. 6:17, and have committed that abomination against God Himself.
The temple was destroyed, and they themselves were abandoned by God, whereby they are no longer the chosen of God. Romans 10
[12] For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him [through faith in Jesus. Rom. 8:8-9]
It seems to me that you have a one-track mindset that God has abandoned the nation of Israel because they killed Jesus.
2 Chronicles 12:19-20 dose not support your thesis. Israel was removed from the Land and the Temple was destroyed because of the continual idolatrous worship of idols by the Nation of Israel.
2 Chron 12:19-20:- 19 “But if you turn away and forsake My statutes and My commandments which I have set before you, and
go and serve other gods, and worship them, 20 then I will uproot them from My [-]land[/-]/fertile soil which I have given them; and this house which I have [g]sanctified for My name I will cast out of My sight, and will make it a proverb and a byword among all peoples.
This visitation of the iniquities of the fathers of the first two ages of the existence of Israel from the time of Isaac's birth began to happen with the Birth of Christ at the beginning of Israel's third age and will continue until the beginning of Israel's fifth age of existence when they will be gathered once more by God to become a Kingdom of Priests, a Holy Nation and God's possession among the nations.
Christ clearly indicates to us in the parable of the barren fig tree, that the nation of Israel will begin to bear fruit when the fig tree is inspected at the very end of the fourth year/age when they begin to repent of their sins of idolatrous worship and the sins of their fathers' idolatrous worship.
Yet you are sowing discord among the brethren with your ignorant words of "wisdom" as to why our brothers before God have done.
You present a thesis that is contrary to God's scriptures and what Jesus also taught concerning what is to happen to Israel.
You present a pointless argument to support your theories.
Goodbye now, as this conversation is going nowhere because of your stubborn nature of holding onto what is not true.
2 Chronicles 12:19-20 does not support your theory that 70 AD occurred because Israel orchestrated the death of Christ on a cross. Rather it tells us that 70 AD happened because of Israel's continuing idolatrous worship.
Please get your facts right before trying to teach others your flawed theories.
