Ezekiel 39:27-29

When I have brought them back from the nations and have gathered them from the countries of their enemies, I will be proved holy through them in the sight of many nations. Then they will know that I am the LORD their God, for though I sent them into exile among the nations, I will gather them to their own land, not leaving any behind. I will no longer hide my face from them, for I will pour out my Spirit on the people of Israel, declares the Sovereign LORD.”
