Thematic Bible: The seventy years' captivity a punishment for neglecting

And them that had escaped from the sword he carried away to Babylon; and they became servants to him and his sons, until the reign of the kingdom of Persia; to fulfil the word of Jehovah by the mouth of Jeremiah, until the land had enjoyed its sabbaths. All the days of its desolation it kept sabbath, to fulfil seventy years.
