2 Chronicles 36:19-21

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