Jeremiah 29:10-12
10
For thus says Yahweh, After seventy years are accomplished for Babylon, I will visit you, and perform my good word toward you, in causing you to return to this place.
11
For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future.
12
You shall call on me, and you shall go and pray to me, and I will listen to you.
