This is the third post in a series on who wrote the book of Daniel. Here you can find Part 1 and Part 2.

From history, we know that Nabonidus was the last king of Babylon before the Medes and the Persians. But according to Daniel 5, Belshazzar was reigning in Babylon the night the kingdom passed to the Medes and the Persians. Until 1929, many scholars believed Belshazzar was a fictional character. In that year R. P. Dougherty published some ancient Babylonian documents that proved that Belshazzar was the son of Nabonidus and ruled Babylon while his father was gone for ten years in Tema in Arabia. The night of the banquet in Babylon when Daniel solved the mystery of the handwriting on the wall, Nabonidus was away fighting the forces of Cyrus. The invading Persians killed Belshazzar (Beaulieu, p. 231).

The Prayer of Nabonidus (PN) is the title of an Aramaic document found among the Dead Sea Scrolls. The text is fragmentary, but enough of the writing remains to reconstruct the basic details of the story. Nabonidus, writing in the first person, says that he suffered from a bad skin disease that God decreed for him. But God forgave his sins and healed him. For seven years, Nabonidus claimed, he had his skin disease while he was worshiping his gods of silver, gold, [bronze, iron], wood, stone, and clay. A Jewish diviner then urged him to give in writing praise and honor to “the name of [the Most High G]od.”

Many scholars have reasoned that the PN is an earlier version of an alleged legend regarding the madness of Nebuchadnezzar (Dan. 4). They point out similarities with the account of Nebuchadnezzar’s affliction as well as with Daniel’s dealings with Belshazzar (VanderKam, pp. 177–178). The starting assumption for those scholars who argue that the PN served as a source for Daniel 4 is that the account of Nebuchadnezzar’s troubles is only a legendary tale.

The account of Nebuchadnezzar’s affliction is a straightforward narrative, but can it stand up to historical scrutiny? Eusebius (early 4th century) quoted Abydenus, a Greek historian, who quoted Megasthenes, a Greek geographer: “[Nebuchadnezzar] went up to his palace, and being possessed by some god or other uttered the following speech: ‘O men of Babylon, I Nebuchadnezzar here foretell to you the coming calamity …. There will come a Persian mule, aided by the alliance of your own deities, and will bring you into slavery. …’ He after uttering this prediction had immediately disappeared, and his son Amil-marudocus [Evil-merodach] became king” (Eusebius, 9.41.6). This tradition shares several features with the biblical account. Nebuchadnezzar uttered the words from his palace; he disappeared from public view immediately following his pronouncement; and he spoke in the first person. The reference to Evil-merodach affords a plausible scenario for what happened to the kingdom while Nebuchadnezzar was incapacitated — his son took it over until his father’s sanity was restored. A fragmentary Babylonian text has a tantalizing reference to Nebuchadnezzar and Evil-merodach (Grayson, pp. 88–89). The line translated “his life appeared of no value to [him]” must refer to Nebuchadnezzar. A few lines later it refers to someone who “does not show love to son and daughter” and “his attention was not directed towards promoting the welfare of Esagil [and Babylon].” Grayson referred these descriptions to Evil-merodach, but Hasel (p. 42) thinks they might “refer to the strange behavior of Nebuchadnezzar during his time of mental incapacity ….” The poor preservation of the text makes it impossible to determine for certain which monarch was meant.

What about the things that happened to Nebuchadnezzar? Did he literally go into the open country and eat grass like animals? Hays (pp. 305–325) refers to Babylonian and Assyrian materials for analogous references to divine judgment reported in images that refer to various animals and birds. “[D]emons and the dead are frequently portrayed with animal characteristics,” but also “the victim can begin to look like the dead even before he or she reaches the underworld” (ibid. 318). Rain and storms also could describe the effect of evil spirits, and in the Bible, rain sometimes indicates suffering as well (Ezra 10:9, 13; Job 24:4–8). Hays notes close parallels between Daniel 4:33 and the story of Ahiqar, which was widely known throughout the ancient Near East (ibid. 320–323; cf. Tobit 1:21–22; 2:10; 11:18; 14:10). When Ahiqar appeared before the king after he went into hiding, he recounted that “the hair of my head had grown down on my shoulders, and my body was foul with the dust, and my nails were grown long like an eagle’s” (p. 323).

Hays concludes that the descriptions of Nebuchadnezzar’s affliction are not “naturalistic” but “impressionistic, poetic evocations of long traditions of prayer.” The images that depict the king living among the animals and taking on animal characteristics “express suffering, lending detail and poignancy to Nebuchadnezzar’s condition” (p. 324). Perhaps the judgments said to have come upon the king were viewed by the original readers as metaphorical for Nebuchadnezzar’s extreme suffering or even demon oppression. Harrison (pp. 1115–1117), by way of contrast, gives a detailed description of a psychological malady that Nebuchadnezzar suffered. At a minimum, Daniel’s account implies that Nebuchadnezzar would be afflicted with an illness or with demons that would render him a social outcast until he recognized that his own reign over Babylon was at the behest of the Most High God. The account is not historically implausible.

Exactly how similar or different are Daniel and PN? There are some important differences. First, the kings were different: Nebuchadnezzar and Belshazzar in Daniel and Nabonidus in PN. Second, the maladies are different: Nebuchadnezzar’s apparent insanity or demonic oppression and Nabonidus’s skin ailment. Third, Daniel warned Nebuchadnezzar before God judged him, whereas the Jewish diviner told Nabonidus to give God glory after God had healed him. Fourth, Nabonidus confessed his worship of false gods for seven years, while Nebuchadnezzar’s pride led to his humiliation before God restored him. The major similarities include the seven periods of time (Daniel) or seven years (PN), the decree of God against a sinful Babylonian king, and a declaration of praise to God after the healing or restoration. Nabonidus was “struck by the decree of G[o]d,” whereas in Nebuchadnezzar’s dream the “decree” about him was by the “determination of holy watchers (angels)” (Dan. 4:17). Nabonidus professed to worshiping “gods of silver and gold, [bronze, iron], wood, stone, clay.” These idols were the same gods that Belshazzar worshiped at his banquet (Dan. 5:4). A Jewish “diviner” either “forgave” Nabonidus’s sin or suggested to Nabonidus that he should write a decree praising the God who forgave his sin. The term for “diviner” in Daniel (2:27; 4:7; 5:7) refers to a category of Nebuchadnezzar’s or Belshazzar’s wise men who could not solve the mystery of the respective king. Belshazzar’s mother encouraged him to consult Daniel, whom “Nebuchadnezzar your father appointed chief of the magicians, conjurers, Chaldeans, and diviners” (Dan. 5:11). Otherwise, Daniel is never called a “diviner.”

Nabonidus was the father of Belshazzar, but the Queen Mother called Nebuchadnezzar Belshazzar’s father. The consensus of the medieval period was that Belshazzar was Evil-Merodach’s son, based on Jeremiah 27:7 (Goldwurm, p. 156; cf. Jerome, p. 55). In the absence of additional information that was a reasonable guess, but the evidence of texts in Babylonian cuneiform that were contemporary with Belshazzar and Nabonidus confirms their relationship. If one interprets Jeremiah 27:7 literally, then it could refer to Evil-Merodach, the son of Nebuchadnezzar, and to Belshazzar if he was in fact the grandson of Nebuchadnezzar (Feinberg, p. 544). Lundbom (p. 316), though, argues that the third generation did not mean a literal son and grandson but only three generations in general.

Dougherty (pp. 39–66) reasoned that a statement in Herodotus showed that Nabonidus was married to Nitocris, a daughter of Nebuchadnezzar by an Egyptian princess and that Belshazzar was, therefore, the grandson of Nebuchadnezzar. As Aramaic bar can mean grandson as well as son, a literal meaning can be given to Belshazzar’s relationship to Nebuchadnezzar as his grandson (cf. Wiseman, pp. 10–12). Likewise ‘ab (father) sometimes means grandfather or ancestor. Some have questioned the accuracy of Herodotus in the matter and opt for a second explanation, namely that ‘ab means predecessor and bar means successor (Steinmann, pp. 261–263). That the queen mother referred to Belshazzar’s “father” three times (v. 11) makes the explanation that Belshazzar was Nebuchadnezzar’s grandson more likely. There is no clear extra-biblical evidence, however, to support that relationship.

The name Nabonidus does not occur anywhere in the Bible or related writings, and even ancient historians such as Herodotus and Xenophon gave confusing information about Nabonidus. Also, they knew nothing of Belshazzar. With so little known about Nabonidus and Belshazzar, why is so much attention paid to them in the book of Daniel and in the PN?

For Daniel, the Babylonian kingdom had a significant part in the scheme of four world powers that would rule until the everlasting kingdom of God overtook them. Belshazzar’s presence at the final banquet was significant for the encounter that Daniel had with him. Since Nabonidus was off fighting the Persians, Belshazzar represented the last sitting monarch of the Babylonian kingdom.

Possibly there is an Idumean/Nabatean background to the PN. It is probable that Nabonidus destroyed the kingdom of Edom in the sixth century B.C. and replaced the king with a Babylonian governor (Bartlett, 2:293). Traditions of this king who decimated Edom even as Nebuchadnezzar decimated Judah could have survived among the Idumeans or Nabateans. The assimilation to elements from the book of Daniel could then have occurred among the Jewish population in Arabia and Edom at that time. Complicating the issue is that in the PN, Tema in Arabia is spelled as Teman, the location of a region in the south of Edom. Steinmann gives another view of the relationship between Daniel 4 and PN. He sees the PN as composed by a Palestinian Jew to supplement the historical gap between Daniel 5 and Daniel 4, with the PN “based on the plot of Daniel 4.”

In conclusion, there is a relationship between the Prayer of Nabonidus and Daniel’s account of Nebuchadnezzar and Belshazzar, but that relationship went from Daniel to the PN. Daniel’s account is older by anyone’s dating of the book, and it sticks more closely to images of illness found in the Ancient Near East. Viewing the Prayer as more ancient than Daniel entails a questionable assumption of the transfer of legendary characteristics of a lesser-known figure to a more well-known figure. And that assumption does not account for the differences between the PN and Daniel 4.
