In that day the Lord will reach out his hand a second time to bring back the remnant of his people— those who remain in Assyria and northern Egypt; in southern Egypt, Ethiopia, and Elam; in Babylonia, Hamath, and all the distant coastlands.

He will raise a flag among the nations and assemble the exiles of Israel. 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 be rivals anymore.
