'Desolation' in the Bible

and do not be like your fathers, and like your brethren, who trespassed against Jehovah, God of their fathers, and He giveth them to desolation, as ye do see.

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.
