Being a Greek word, diaspora only occurs in the NT and only three times:

Jas 1:1 « James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting. »
1Pe 1:1 « Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, »
Then there's « diaspero » which occurs in Acts 8:1, Acts 8:4, Acts 11:19 where it's translated as « scattered abroad ». In Acts « diaspero » points to the persecution by Saul, so this is not what we usually think of in context with diaspora.
The Hebrew word for diaspora is « poots » and occurs a lot of times and is translated mostly as « scattered » or « scattered abroad », for example in Gen. 11:4:
Gen 11:4 « And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth. »
The first time it is used of Israel is:
Deu 30:3 « That then the LORD thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the LORD thy God hath scattered thee. »
This points to the « diaspora », because of the « all the nations », and the length is not known, we only know when it started: 70 AD.
Then there is the Babylonian and Assyrian captivity which AFAIK is not called a diaspora, because although the were taken out of the country, they were taken to one place (Babylon or Assyria) and not scattered.
It is God who keeps Israel intact even while scattered:
1Sa 12:22 « For the LORD will not forsake his people for his great name's sake: because it hath pleased the LORD to make you his people. »
I think - based on observation of history - the only help Israel gets now is preservation, otherwise Satan would destroy them completely so there is nothing for the Lord to return to in His second coming. I'm aware this is brief and far from complete but it's the best I can do for now.
