Don't be ridiculous. The destruction of the temple in 70 A.D. in no way represents the rebuking of the devourer mentioned in Malachi. You make a mockery of God's word in saying this.
The reality is simple...that the scribes and Pharisees, while they gave a tenth of anise and cumin and other spices, neglected the weightier matters of the law...and this they should have done without leaving the other undone.
The temple was destroyed in 70 A.D. not because they tithed and this was the devourer coming against the reality of God's word...no.
The temple was destroyed because Israel did not recognize the time of her visitation.
You attempt to make the word of God null and void by your statements; and in doing so you are doing the work of the devil himself.
The temple came down for a these reasons.
1. As in the wilderness for forty years unbelievers were not allow to go into the promise land. 70 AD would be approximately forty years from Jesus being put on the cross.
2. The scribes and Pharisees, who took over the temple were, as Jesus pointed out, children of the devil, not the children of Israel. As such they desecrated it.
3. Put a total end to the age of Law.
One can learn a lot by reading Flavius Josephus writings, The Wars of the Jews.
