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. For 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. Then you will call upon me and come and pray to me, and I will hear you. You will seek me and find me, when you seek me with all your heart.” – Jeremiah 29:10-13
The Lord had given a great revelation to the prophet Jeremiah in the midst of the harshest trial of his life. It was through this revelation that he was told that Babylon’s days of rule would come to an end. The tyranny would be short lived, seventy years. When Babylon would fall Judah’s punishment would end and restoration would begin. Then God would keep His promise and return the exiles to their land.
