Jeremiah 29:9-13
English Standard Version
10"For thus says the Lord: When seventy years are completed for Babylon, I will visit you, and I will fulfill to you my promise and bring you back to this place.
11For I know the plans I have for you, declares the Lord, plans for welfare and not for evil, to give you a future and a hope.
12Then you will call upon me and come and pray to me, and I will hear you.
13You will seek me and find me, when you seek me with all your heart.
