Jeremiah 29:10-14 (NKJV)
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. 13 And you will seek Me and find Me, when you search for Me with all your heart. 14 I will be found by you, says the Lord, and I will bring you back from your captivity; I will gather you from all the nations and from all the places where I have driven you, says the Lord, and I will bring you to the place from which I cause you to be carried away captive.
