Isaiah speaks of a “second” return.

Isaiah 11 speaks of the times of the Messiah in the early part of the chapter of the times of the Messiah, and indeed of future heavenly times.

“The wolf shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fattened calf together; and a little child shall lead them.”
Isa 11:6

There is much more to study and to say here, but notice that Isaiah speaks of a SECOND return (say around the year 700 BC), before the first one started in 538 BC. The Jews are pictured as scattered all over the world, and Isaiah says,

“It shall happen in that day, that the Lord will set his hand again the second time to recover the remnant of his people, who shall remain, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea.”
Isa 11:11

Some have said, that this is referring the times of Zerubbabel and Ezra and Nehemiah; and the first return was when Israel had her Exodus out of Egypt. But NO! This second return in Isaiah 11 is also from Assyria and many other nations, including from “the islands of the sea.”

So Isaiah clearly forecasts a second return of the Jews to Palestine, from, evidently, the scattering among the nations after the scattering of the Jews by Assyria and Babylon in the 8th, 7th, and 6th centuries BC.

Then comes the text in Zechariah 10

Written after the first return of the Jews to Palestine, and while the Jews are still working to establish themselves in Palestine, Zechariah says that once more God will once more scatter the Jews among the nations. The following quote from the WEB says God will “sow” the Jews among the nations, and THEN they will remember their God.

“I will sow them among the peoples;
And they will remember me in far countries;
And they will live with their children, and WILL return.”
Zech 10:9 (emphasis added)

A second scattering/sowing of Israel among the nations? It has to talking of the time of the revolts in 70 AD, and the Bar Kochba revolt of the early second century AD when the Jews ended up being forbidden to return to Jerusalem. Then Zechariah tells of a second return.

“I will bring them again also out of the land of Egypt,
And gather them out of Assyria;
And I will bring them into the land of Gilead and Lebanon;
And there won’t be room enough for them.”
Zech 10:10

Is this speaking the return that began in late 19 century AD and continuing even into our times. It certainly looks like it. The last half of that verse, that there will be so many of them that they will run out of room, clearly hasn’t happened YET!
