If only, in this chapter, we could say the same of Belshazzar that we said of Nebuchadnezzar in chapter 4, the very opposite is true! His actions deliberately insult and blaspheme God even though he knew all about his grandfather’s life, but he was not willing to learn from it.
“Immediately the fingers of a human hand appeared and began writing on the plaster of the wall of the royal palace, next to the lampstand. The king was watching the hand as it wrote.”
Daniel 5:5 NRSV
