'Seventy Years' in the Bible

And it will be in that day that Tyre will go out of mind for seventy years, that is, the days of one king: after the end of seventy years it will be for Tyre as in the song of the loose woman.

And it will be after the end of seventy years, that the Lord will have mercy on Tyre, and she will go back to her trade, acting as a loose woman with all the kingdoms of the world on the face of the earth.
