2 Chronicles 36:19-21

19And they burnt the house of God, and broke down the wall of Jerusalem, and burnt all its palaces with fire, and destroyed all its precious vessels. 20And them that had escaped from the sword he carried away to Babylon; where they were servants to him and his sons until the reign of the kingdom of Persia:1 21To fulfil the word of the LORD by the mouth of Jeremiah, until the land had enjoyed its sabbaths: for as long as it lay desolate it kept sabbath, to fulfil seventy years.
