This is what the Sovereign LORD says:  O my people, I am going to open your graves and bring you up from them; I will bring you back to the land of Israel.  Then you, my people, will know that I am the LORD, when I open your graves and bring you up from them.  I will put my Spirit in you and you will live, and I will settle you in your own land. Then you will know that I the LORD have spoken, and I have done it, declares the LORD. 

Ezekiel 37:12-14   (NIV)
