Jeremiah 29:10-12 (New King James Version)

 ¹⁰ For thus says the LORD: After seventy years are completed at Babylon, I will visit you and perform My good word toward you, and cause you to return to this place. ¹¹ For I know the thoughts that I think toward you, says the LORD, thoughts of peace and not of evil, to give you a future and a hope. ¹² Then you will call upon Me and go and pray to Me, and I will listen to you.
