Jeremiah 25:12

When seventy years are accomplished; seventy years accounted from the time that the Jews were carried away in the time of Jeconiah or Jehoiachin, 2 Kings 24:15,16. This was fulfilled by Darius the king of Persia, Daniel 4:31. Of these seventy Nebuchadnezzar reigned thirty-six, 2 Kings 25:27, Evil-merodach thirty-two, and Belshazzar at least two, Daniel 8:1. Though God, whose all the creation is, and who is the Lord of all the hosts of his creatures, doth often make use of heathens and other wicked men to punish his own people, yet he will at last punish them too; and ordinarily when he doth punish them, it is with a more severe and grievous destruction than that by which he punisheth his people, Isaiah 27:7; thus he threatens to make the Chaldeans a perpetual desolation.
