Thanks, you're right about it being 5th century BC. I'm just used to seeing Judean or Yehudim, and palestinian kind of rubs me the wrong way, because of the agenda during the last 60-70 years.
On the 2nd exodus though, I don't believe it will occur until after the tribulation, when the house of Judah, and the house of Ephraim (Northern kingdom of Israel) are regathered for the millennial Kingdom, after a period of protection in the wilderness.
Our Father couldn't have reconciled with Ephraim before the resurrection of the Messiah, because of the statutes regarding divorce and remarriage. He would have divorced Judah too, because of her sin, if it weren't for the promise He made to David. Once the Messiah was resurrected, he was eligible to marry Judah and Ephraim.
The whole Exodus story is a veiled picture of the end times. Compare the plagues of Egypt, with the plagues of Revelation. Compare the angel with the censer of fire in Rev.8, to Aaron with the censer of fire, or protection in the wilderness in Rev. 12:14, to Deut. 32:10,11.
A lot of the regathering scriptures are what people see as the erroneous rapture theology.
I'm sorry for getting off the topic of your book. I didn't get see enough of it to know the content.
