Who was King Belshazzar?

Understanding Daniel 5:1-31

Belshazzar is one of the most dramatic figures in the Old Testament — a king who received the most terrifying message in all of Scripture, written by a disembodied hand on his palace wall, and who was dead before morning. His story in Daniel 5 is the origin of the phrase 'the writing on the wall,' and it marks the end of the Babylonian Empire.

Historical Background

For centuries, critics dismissed Belshazzar as a biblical fiction because ancient Greek historians (Herodotus and Xenophon) named Nabonidus as Babylon's last king — and never mentioned Belshazzar. Then, in 1854, archaeologists discovered the Nabonidus Cylinder and other cuneiform texts that confirmed Belshazzar was real. He was the son of King Nabonidus and served as co-regent in Babylon while Nabonidus lived in self-imposed exile in the Arabian oasis of Tayma for about ten years.

This historical detail explains a puzzle in Daniel 5. When Belshazzar rewards Daniel, he makes him 'the third highest ruler in the kingdom' (5:29) — not second. Why third? Because Nabonidus was first (though absent), Belshazzar was second (ruling in Babylon), and the highest position Belshazzar could grant was third. The Bible preserves a historical detail that was lost to Greek historians but confirmed by archaeology.

The Banquet

'King Belshazzar gave a great banquet for a thousand of his nobles and drank wine with them' (Daniel 5:1). The timing was extraordinary — the Persian army under Cyrus the Great was already besieging Babylon. Belshazzar's feast was an act of either supreme confidence or deliberate defiance. Babylon's walls were considered impregnable: double walls, the Euphrates River flowing through the city, massive food stores. The city could outlast any siege — or so they believed.

Then Belshazzar escalated from foolishness to sacrilege: 'While Belshazzar was drinking his wine, he gave orders to bring in the gold and silver goblets that Nebuchadnezzar his father had taken from the temple in Jerusalem, so that the king and his nobles, his wives and his concubines might drink from them' (5:2). 'Father' here means predecessor/ancestor — Nebuchadnezzar was likely his grandfather or great-grandfather through his mother's line.

These vessels had been consecrated to the God of Israel. Using them as party cups while praising 'the gods of gold and silver, of bronze, iron, wood and stone' (5:4) was a direct insult to the God who had judged Nebuchadnezzar before him. Belshazzar knew this history — Daniel later confronts him: 'But you, Belshazzar, his son, have not humbled yourself, though you knew all this' (5:22).

The Writing on the Wall

'Suddenly the fingers of a human hand appeared and wrote on the plaster of the wall, near the lampstand in the royal palace. The king watched the hand as it wrote. His face turned pale and he was so frightened that his legs became weak and his knees were knocking' (5:5-6).

Belshazzar's terror was absolute. He summoned his enchanters, astrologers, and diviners, promising that whoever could read and interpret the writing would be clothed in purple, receive a gold chain, and become third ruler in the kingdom. None could interpret it.

The queen mother (likely Nitocris, Nabonidus' wife) remembered Daniel: 'There is a man in your kingdom who has the spirit of the holy gods in him. In the time of your father he was found to have insight and intelligence and wisdom like that of the gods' (5:11). Daniel was brought in.

Daniel's Interpretation

Daniel refused the gifts but read the writing: MENE, MENE, TEKEL, UPHARSIN (or PARSIN). These were Aramaic words with double meanings — they were units of weight/currency AND carried verbal meanings:

• MENE ('numbered'): 'God has numbered the days of your reign and brought it to an end' (5:26).
• TEKEL ('weighed'): 'You have been weighed on the scales and found wanting' (5:27).
• PERES/UPHARSIN ('divided' — also a wordplay on 'Persia'): 'Your kingdom is divided and given to the Medes and Persians' (5:28).

The message was God's verdict: judgment is complete, the sentence is passed, and execution is imminent.

Before interpreting, Daniel delivered a devastating sermon. He recounted how Nebuchadnezzar had been humbled by God — driven to live like an animal until he acknowledged that 'the Most High God is sovereign over all kingdoms on earth' (5:21). Then Daniel turned to Belshazzar: 'But you, Belshazzar, his son, have not humbled yourself, though you knew all this. Instead, you have set yourself up against the Lord of heaven' (5:22-23). Belshazzar's sin was not ignorance — it was defiance with full knowledge.

The Fall of Babylon

'That very night Belshazzar, king of the Babylonians, was slain, and Darius the Mede took over the kingdom' (5:30-31). According to the Greek historians Herodotus and Xenophon (and confirmed by the Nabonidus Chronicle), the Persians diverted the Euphrates River upstream, lowering the water level where it flowed under Babylon's walls. Persian soldiers waded through the riverbed and entered the city at night, encountering minimal resistance because the Babylonians were celebrating a festival — likely the very banquet described in Daniel 5.

The greatest city in the ancient world fell in a single night, exactly as the prophets had predicted (Isaiah 13:17-22; Jeremiah 51:39-40).

Theological Significance

Belshazzar's story teaches several enduring lessons:

1. Knowledge without humility is fatal. Belshazzar knew what happened to Nebuchadnezzar. He had the evidence. He ignored it. 'Though you knew all this' is the most condemning phrase in the chapter.

2. God's patience has limits. Nebuchadnezzar was given years and multiple chances to repent. Belshazzar received one night — and a wall.

3. Desecrating the sacred invites judgment. The holy vessels represented God's covenant presence. Using them to toast pagan gods was the final provocation.

4. Human kingdoms are accountable to God. The God of Israel weighed the greatest empire on earth and found it wanting. No political power is exempt from divine judgment.
