Book of Mormon Evidence: Near Eastern Weights and Measures

In Alma 11:1–19, Mormon provides readers with an explanation of the Nephite monetary system that was established by King Mosiah. This system of exchange was based on pieces of gold and silver that were convertible into measures of barley or other types of grain. In various ways, Mosiah’s monetary system relates well to systems of weights and measures from the ancient Near East. The following chart presents each of the Nephite units of gold and silver, their equivalents in measures of grain, and their mathematical ratios (in relation to the smallest unit):¹

An Absence of Coins

The text of the Book of Mormon never mentions coins or coinage.² Instead, the Nephite system discusses the “measure” and “reckoning” of “different pieces of their gold, and of their silver, according to their value” (Alma 11: 4; emphasis added). This absence of coinage is consistent with the monetary practices in ancient Israel and other Near Eastern societies both before and during Lehi’s day. As explained by Raz Kletter, “It was a world without coins, without money—or nothing that we today define as money. No coins of gold or silver with heads of rulers, no cheque books, no banknotes and no plastic credit cards. The value of commodities was largely determined by contents in volume or weight.”³ Only after Lehi and his family left were coins introduced into Israel and its surrounding regions.⁴

Silver and Gold

Weighted measures of gold and silver served as the primary basis for exchange for several ancient Near Eastern societies, just as they did in the Book of Mormon.⁵ In Mesopotamia, where first silver and later gold provided base standards of value,⁶ there is good evidence that silver was used fairly extensively and directly (although not exclusively) as a medium of exchange.⁷

While Egypt also dealt in silver and gold, it is assumed that in this region commodities were more often bartered. Even in situations where no gold or silver was actually changing hands, however, the “value of the exchanged goods [was] measured in quantities of metal.”⁸ This may have been the case in the kingdom of Judah as well, which also traded in gold and silver (especially at the national and international level) but where “day-to-day transactions in small communities were most probably made by exchange (barter), which did not necessitate formal weighing and actual exchange of precious metals.”⁹

Whether or not metals were directly used in most economic transactions among the Nephites, the principle of metal equivalency was key to their economy, in which a “senum of silver was equal to a senine of gold, and either for a measure of barley, and also for a measure of every kind of grain” (Alma 11:7; emphasis added).

Barley and Every Kind of Grain

The fact that barley is the only grain mentioned by name in the Nephite system suggests it was a primary commodity of exchange. Barley also played an important role in many ancient Near Eastern economies.¹⁰ For instance, the Law of Eshnunna (from Babylon) opens with an equivalency between a measure of barley and a weight of silver: “1 kor of barley is (priced) at 1 shekel of silver.”¹¹ As noted by John W. Welch, “A similar conversion between silver and barley was also used among the Hittites.”¹² One study has even proposed that a measure of barley provided the most fundamental basis for ancient Near Eastern weights and measures.¹³

Other commodities, including wheat and various other grains, also had standardized measures.¹⁴ In fact, many Mesopotamian weights themselves were shaped as seeds of grain. “This shape proved so popular that it became common in Phoenicia (Byblos, Ugarit, Sarepta, Alalakh), Cyprus and even Egypt.”¹⁵ Thus, the inclusion of equivalencies for “every kind of grain” in the Nephite system is consistent with ancient systems (Alma 11:7).¹⁶

Fractions

The Nephite monetary system expresses several units as fractions: shiblon (¹/₂), shiblum (¹/₄), leah (¹/₈). None of these have a numerator greater than 1 and all are described as merely being half the value of another weight (Alma 11:15–17). The simplicity of this system works in its favor. As noted by John Bosak, “the ancients were notoriously bad with fractions, so any system of relationships must have been based on the simplest of ratios that workably represented the average densities of actual trade goods.”¹⁷

Along similar lines, Welch noted that “arithmetic had not developed far enough in ancient times to allow for the full expression of complex fractions or mixed integers and fractions in other cultures. People in the ancient Near East knew how to say ¹⁄₂, ¹⁄₄, or ¹⁄₁₀, but if an ancient Egyptian or Greek wanted to say ³⁄₈, he would usually have to say ‘one fourth plus one-eighth.’”¹⁸ This practice is reminiscent of the gold antion among the Nephites. While technically being 1¹⁄₂ times the value of the system’s base units (senine and senum), the text avoids describing it as a mixed fraction and instead presents it as a multiple of a lesser unit: “Now an antion of gold is equal to three shiblons” (Alma 11:19).  

As a final fraction-related resemblance, it is interesting that just like Mosiah’s system of exchange, some other ancient Near Eastern systems used just three units that were a fraction of the base standard. This is true for a system derived from limestone weights from Judah (based on the shekel),¹⁹ as well as a two-standard system reconstructed from examples of Egyptian weights (based on the qdt and dbn).²⁰ The progression of each system’s standardized values (from least to greatest) is given in the chart below:

Doubling Principle

The Nephite monetary system operates on the principle of binary progression, where most units of measure (except the limnah, onti, and antion) are twice or half the value of another unit. Various applications of this doubling principle, including extended binary progressions, can also be found in other ancient Near Eastern systems of weights and measures.

For instance, the limestone weights from Judah (presented in the chart above) have values of ½, 1, 2, and 4—just like the Nephite system. It also has 8 (a double of 4) and 16 (a double of 8), as well as 12 and 24, which also half or double one another. While this system primarily progresses on multiples of 4 and 8, doubling is present throughout.²¹

More akin to the Nephite system, an ancient Arabian system in use as early as the 5th century BC, has seven units that progressively double one another:²²

2 kyš = 1 šśʿ

2 šśʿ = 1 tmrt

2 ʾtmr = 1 gms

2 ʾgms = 1 nṣf

2 ʾnṣf = 1 K

2 K = 1 ʾrbʿt 

An Egyptian system features a similar progression, although expressed as fractions.²³ As explained by Welch,

In ancient Egypt, the heqat was a full measure of grain. The fractions of the heqat were ¹⁄₂, ¹⁄₄, ¹⁄₈, ¹⁄₁₆, ¹⁄₃₂, and ¹⁄₆₄. As in the Nephite system, the Egyptian grain measures were binary—fractions that came about by halving. In Egyptian hieroglyphs, these fractions “were written in a special way, quite unlike ordinary fractions.” … In other words, the pupil of the eye became the hieroglyph for ¹⁄₄; the eyebrow, ¹⁄₈; the eyelash, ¹⁄₃₂; the tear duct, ¹⁄₆₄; and so on.²⁴

Additive Principle

According to Welch, “The full Horus-eye then symbolized the full measure of grain, or in other words the wdjt-eye was the sum of them all.”²⁵ This additive principle is also present in Mosiah’s monetary system. After explaining the relative values for the gold units (the senine, seon, and shum), Mormon explained that the “limnah of gold was the value of them all” (Alma 11:10). Likewise, after detailing the silver units (the senum, amnor, and ezrom), it is reported that the “onti was as great as them all” (Alma 11:13).²⁶

To a lesser extent, the additive principle is also present in the Judean system based on the shekel:²⁷

While not the value of all lesser units, the final unit in this system (#11) is still the sum of various groupings of lesser units:²⁸ 

• #11 = #10 + #9
• #11 = #10 + #8 + #6
• #11 = #9 + #8 + #7 +#6

Conclusion

Various descriptions of weights and measures are found throughout the Bible, yet the relationships among these units aren’t apparent from the text itself. Concerning the biblical shekel, Raz Kletter explains, “The trouble is that we have no information in the Old Testament on the relationships between its weight units.”²⁹ It is thus unlikely that the units and conversion ratios present in Mosiah’s system were derived from biblical evidence.

Even if the Bible did contain all the information needed to reconstruct its weight and measures, Mormon noted that the Nephites didn’t “measure after the manner of the Jews; but they altered their reckoning and their measure, according to the minds and the circumstances of the people, in every generation, until the reign of the judges, they having been established by king Mosiah” (Alma 11:4). It therefore shouldn’t be a surprise that Mosiah’s monetary system is not a perfect match with any known system of ancient weights and measures.

On the other hand, as a system purportedly created by displaced Israelites, one might still expect the Nephite system of exchange to resemble features of Judean weights and measures, or perhaps other Near Eastern systems. And this it does on numerous points: (1) the lack of coinage, (2) the use of gold and silver, (3) equivalencies between metals and grains, (4) barley’s prominent status, (5) the usage of both whole numbers and fractions, (6) the use of just three fractional units (7) the avoidance of expressing a mixed fraction, (8) binary progression, and (9) a final unit that is the sum of the system’s lesser units. This assemblage of parallels suggests that the Nephite’s economic system may have been modeled to some degree after Near Eastern precedents.
