IF one were a dispensationalist these are the scriptures they would use:
Diaspora and return
Hosea 3:4-5 - For the Israelites will live many days without king or prince, without sacrifice or sacred stones, without ephod or idol. Afterward the Israelites will return and seek the LORD their God and David their king. They will come trembling to the LORD and to his blessings in the last days.

Ezekiel 36:11; 24 KJV - And I will multiply upon you man and beast; and they shall increase and bring fruit: and I will settle you after your old estates, and will do better [unto you] than at your beginnings: and ye shall know that I [am] the LORD....
