2 Chronicles 36:21

To fulfil the word of the LORD by the mouth of Jeremiah, until the land had enjoyed her sabbaths: for as long as she lay desolate she kept sabbath, to fulfil threescore and ten years.

to fulfill the word of Yahweh by the mouth of Jeremiah, until the land had enjoyed its Sabbaths: [for] as long as it lay desolate it kept Sabbath, to fulfill seventy years.

to 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.

to fulfil the word of Jehovah in the mouth of Jeremiah, till the land hath enjoyed its sabbaths; all the days of the desolation it kept sabbath -- to the fulness of seventy years.

So the land enjoyed its Sabbath rest all the days of the desolation, until seventy years were completed, in fulfillment of the word of the LORD through Jeremiah.
