Question: where does the saying writing on the wall come from

title: Belshazzar's feast
text: Belshazzar 's feast , or the story of the writing on the wall ( chapter 5 in the Book of Daniel ) tells how Belshazzar holds a great feast and drinks from the vessels that had been looted in the destruction of the First Temple . A hand appears and writes on the wall . The terrified Belshazzar calls for his wise men , but they are unable to read the writing . The queen advises him to send for Daniel , renowned for his wisdom . Daniel reminds Belshazzar that his father Nebuchadnezzar , when he became arrogant , was thrown down until he learned that God has sovereignty over the kingdom of men . Belshazzar had likewise blasphemed God , and so God sent this hand . Daniel then reads the message and interprets it : God has numbered Belshazzar 's days , he has been weighed and found wanting , and his kingdom will be given to the Medes and the Persians .
