In that day the Lord will bring back a remnant of his people for the second time, returning them to the land of Israel from Assyria, Lower Egypt, Upper Egypt, Ethiopia, Elam, Babylonia, Hamath, and all the distant coastlands.
References for Isaiah 11:11
He will raise a flag among the nations for Israel to rally around. He will gather the scattered people of Judah from the ends of the earth.
Then at last the jealousy between Israel and Judah will end. They will not fight against each other anymore.
