The Bible Says
Daniel 5:29-31 Meaning

Despite hearing that his kingdom is going to end, Belshazzar keeps his word. This is another irony. The arrogant king does not reject the unwelcome message. Perhaps he hopes that by acknowledging God, he can be spared judgment. He gives orders to fulfill the promised reward for anyone who could interpret the writing on the wall, and that person is Daniel. So Daniel is clothed with purple and has a necklace of gold placed on his neck. Daniel rejected these rewards up front, prior to interpreting the writing, but they are bestowed on him, regardless of his preference.

Belshazzar gave orders to other servants to bestow the gifts on Daniel. In addition to the fine clothes and jewels, Daniel is given authority as third ruler in the kingdom by way of a proclamation from Belshazzar. This will be short-lived, since now it is clear that God will give Babylon to the Medes and Persians. Still, it is consistent with Daniel's career. His entire life in Babylon has been marked by his gift of interpreting God's revelations to the kings, and being promoted and exalted every time.

This new promotion, the most meteoric rise in power of them all, is brief in Babylon. God's message was timely and true, for that same night Belshazzar the Chaldean king was slain. The Mede and Persian armies took the city of Babylon, and Belshazzar was immediately killed in the conquest.

Darius the Mede received the kingdom subsequent to Belshazzar's death. The passage concludes with this transition of power. Although Daniel's rise to power in the Babylonian kingdom was brief, the next chapter opens with Daniel in a high position. When the Persians came under the wall and took the city, very few lives were taken. Virtually the entire city was captured. We can imagine Darius interviewing the king and his nobles, who were conveniently assembled together, and learning of the story of Daniel predicting the fall of Babylon to the Medes and Persians. So although Daniel's reign as third ruler was brief, it may have catapulted him to prominence in Darius' administration.

Daniel survives and continues serving in Babylon, while remaining faithful to his God. A stranger in a strange land-living in the world, but not of it.
