Jeremiah 29:10-14

 10 “For this is what the Lord says: ‘When seventy years have been completed for Babylon, I will visit you and fulfill My good word to you, to bring you back to this place. 11 For I know the plans that I have for you,’ declares the Lord, ‘plans for prosperity and not for disaster, to give you a future and a hope. 12 Then you will call upon Me and come 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 let Myself be found by you,’ declares the Lord, ‘and I will restore your fortunes and gather you from all the nations and all the places where I have driven you,’ declares the Lord, ‘and I will bring you back to the place from where I sent you into exile.’ Jeremiah 29:10-14
