—>> why were the conquerors of Biblical Israel greatly blessed? like Rome (1000 year empire with the blessings of birth of Christianity), while Israel’s allies were annihilated?
Not a new question.
Your assumptions are incorrect though.
Jeremiah 12:1
Righteous are You, O Lord, that I would plead my case with You;
Indeed I would discuss matters of justice with You:
Why has the way of the wicked prospered?
Why are all those who deal in treachery at ease?
“Righteous are You, O Lord, that I would plead my case with You;
Indeed I would discuss matters of justice with You:
Why has the way of the wicked prospered?”
In the case of Israel, the wicked did not prosper, because the Israelis became moloch worshipping pieces of garbage so God richly blessed the nations that disciplined those people.
In New Testament God made it clear they had served their purpose, bring his son and salvation to the world and tore the curtain in half.
Those people were wickedly persecuting the Bride of Christ, so in 70 AD, God used the Roman Empire to bring the final end.
Since then, there has not been any more 12 tribes any more, as there had been for 2000 years before. There never will be 12 tribes again.
