Why You Should Care About the Nephite Weights and Measures System

“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

The Know

When king Mosiah, the son of king Benjamin, died he did not appoint someone to succeed him as king (Alma 1:1).1 Instead, he established a legal code and a system of judges to enforce the law (Alma 11:1–2).2 In this new law, Mosiah specified that the judges should be paid for their time (see Alma 11:1). However, John W. Welch has explained that, in order to do this, Mosiah would have needed to standardize a system of weights and measures to make sure all the judges were actually getting paid fairly.3

Before this time, the Nephites simply adapted their system of measurement “according to the minds and the circumstances of the people, in every generation” (Alma 11:4).4 Mosiah helped end the confusion by standardizing the “exchange ratios for gold, silver, barley, and all kinds of grain (see Alma 11:7).”5

However, there is an ancient Near Eastern precedent for this kind of standardization.6 As Welch has noted, the ancient Mesopotamian laws of Eshnunna began with a list of “exchange equivalencies” such as “1 kor barley for 1 shekel silver.” Welch further explained, “The laws of Eshnunna established fixed silver values for oil, salt, wool, copper, sesame oil, and lard.” The list of equivalences that introduces the laws of Eshnunna is remarkably similar to the Book of Mormon.7

King Mosiah's system in Alma 11:3–19 resembles Eshnunna’s, even down to the phrasing of the list. Welch observed that “the standard phrasing ‘One kor of barley is (priced) at one shekel of silver’ resembles ‘A senum of silver was equal to a senine of gold’ (Alma 11:7).”8 Interestingly, the “primary conversion in ancient Babylonia was between barley and silver,” just as it was in the Book of Mormon (Alma 11:7).9

Welch further noted that the introductory list in the laws of Eshnunna converts some goods “into silver values, followed by three more provisions that convert others into measures of barley. Thus, precious metal and grain measures were convertible into each other.”10 The laws of Mosiah appear to have been the same in this respect: “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).11 Both systems even allowed people to sell a variety of goods while still measuring their values in terms of gold, silver, or barley.12

Even the motivations behind the two laws appear to have been similar—to standardize daily wages for certain professions.13 The laws of Eshnunna set prices for the labor of people like harvesters and boatmen,14 just like king Mosiah set a specific wage for judges: “And the judge received for his wages according to his time—a senine of gold for a day ... and this is according to the law which was given” (Alma 11:3).15

The Why

Because the laws of Eshnunna were not discovered until the mid-twentieth century, the similarities between Mosiah’s and Eshnunna’s law codes are a subtle reminder of the authenticity of the Book of Mormon.16 However, much more than that, the similarities speak volumes about the kind of ruler King Mosiah was. Just as ancient Near Eastern law codes were meant to establish justice and protect the weak, Welch has noted, “King Mosiah enacted his laws expressly to establish peace and equality in the land (see Mosiah 29:38, 40).”17

His desire to standardize the weights and measures show that he was serious about providing a fair wage for the judges who would replace him.18 This detail may help to explain, in small part, why Mosiah’s people “did wax strong in love” towards him, and “did esteem him more than any other man.” His actions showed that he was not “a tyrant who was seeking for gain, yea, for that lucre which doth corrupt the soul; for he had not exacted riches of them.”19 His laws had helped to create “peace in the land,” so his people “did esteem him, yea, exceedingly, beyond measure” (Mosiah 29:40).

This standardization changed Nephite society in significant ways and could have led to a just and stable political system. Unfortunately, the new system was soon corrupted, with judges artificially attempting to give themselves more work, leading to predictably disastrous results. However, nobody can blame Mosiah for the corruption of a just system.20

The similarities between the laws of Eshnunna and Mosiah’s law code highlight Mosiah’s desire to create justice, peace, and equity throughout his kingdom, but they also show the reader something else about him.21 If his desire to have his line end with him had simply been an act, he almost certainly would not have prepared so carefully for those who were to follow him in leadership. His careful attention, even to the wages of the judges, shows his genuine concern for the survival of the new judgeship for future generations.22
