Abstract

The allegory of the olive tree, recorded in Jacob 5, contains many details that are consistent with known botanical principles and horticultural practices.

Zenos’s allegory of the olive tree recorded in Jacob 5 contains, by far, the most extensive discussion of olive horticulture found anywhere in scripture. While some of its olive-related details can also be found in biblical texts, many others couldn’t have been derived from any biblical source or combination of sources.1 This provides a unique opportunity to test the Book of Mormon’s content, in this case on botanical grounds.

In 1990, Wilford M. Hess, a professor of botany, compared Zenos’s allegory with known facts and principles pertaining to the cultivation of olive trees.2 Several years later, Hess, along with additional researchers, significantly expanded upon his original work.3 They concluded that “Nearly all of the allegory in Jacob 5 corresponds exceptionally well with both ancient and modern botanical principles and horticultural practices.”4 The following sections present just a sampling of such correspondences, most of which relate to the principle of grafting.

Wild and Tame Trees

Most modern translations of Paul’s statements in Romans 11:24 contrast a “wild” olive tree with a “cultivated” olive tree.5 While this dichotomy is somewhat obscured in the King James Bible,6 it is presented throughout Jacob 5,7 in which the “wild” olive tree is paired in opposition to a “tame” olive tree.8 These descriptions correlate well with known species of olive trees. According to Hess, et al., “When branches of a wild olive tree are grafted onto a tame olive tree (Jacob 5:10), we assume that this is analogous to grafting a wild species (O. oleaster) onto a domesticated species (O. europaea).”9

Young and Tender Branches

The Lord of the vineyard hoped that his efforts to care for his decaying tame tree would cause it to “shoot forth young and tender branches” so that it would “perish not” (Jacob 5:4). These tender branches most likely correspond to what are called suckers in modern vernacular, which grow from the roots or lower portions of a trunk of an existing tree. Importantly, the proliferation of these new shoots tends to be accelerated by extensive pruning, as was carried out by the Lord of the vineyard to save his tame tree.10 As explained by Hess, et al.,

Old trees that are apparently dying, if properly tended, can become vigorous, high-yielding, renewed trees with only elementary care (cf. Jacob 5:8). When the lower portion of a tree has some vitality left, only the diseased, decayed, or dead portions are removed (see Jacob 5:7). New growth starts again at varying speeds. In favorable circumstances, new shoots form a new framework within a few years and trees will resume normal fruiting after four to five years.11

Grafting Young and Tender Branches

Concerning the “young and tender branches” beginning to grow on the tame tree, the Lord of the vineyard stated, “I take away many of these … and I will graft them whithersoever I will; and it mattereth not that if it so be that the root of this tree will perish, I may preserve the fruit thereof unto myself” (Jacob 5:8).

Grafting involves taking material from one plant (a branch, twig, or bud) and inserting it into a portion of another plant and then binding them in some manner. This allows their tissues to fuse together over time, so that a branch of one variety of plant may be stabilized by the trunk and nourished by the root system of another. Importantly, “Each cell of any branch will remain genetically the same as the parent tree from which it was cut.”12 This helps explain what the Lord meant by saying that he would “preserve the fruit” of his tame olive tree by grafting its shoots into other plants. Any fruit grown on such grafts would be genetically identical (and therefore visibly and constitutionally similar) to the tame tree from which they were taken.

Grafting Wild Branches

After removing the “young and tender branches” from the tame tree and grafting them elsewhere, the Lord of the vineyard said to his servant, “Take thou the branches of the wild olive tree, and graft them in, in the stead thereof” to “preserve the roots thereof that they perish not” (Jacob 5:9, 11). 

Although it would … have been unusual for an olive grower to graft wild branches onto a tame tree, circumstances exist when it makes good sense to do so. Due to the vigor and disease resistance of certain wild species, grafting wild stock onto a tame tree can strengthen and revitalize a distressed plant …. Zenos’s allegory portrays the Lord of the vineyard as somewhat exasperated, trying all available options to revive his old, beloved tree, including the extraordinary step of experimenting to see if any good might come by grafting wild stock onto the branches of the natural tree.13

Grafting/Planting Olive Branches

Concerning the branches from the tame olive tree, the Lord initially stated his intention to “graft them whithersoever I will” (Jacob 5:8). Yet, later the text repeatedly speaks of these branches being planted, as in verse 25: “Behold, this have I planted in a good spot of ground.”14These descriptions of both grafting and planting olive branches are botanically accurate.

The ancients relied principally upon propagation by slips, which is accomplished by taking stem pieces or cuttings of roots and burying them in an inclined position in trenches four inches deep. They normally sprout within a year. The olive is one of the few fruit trees that can be propagated by taking a branch of a tree and burying it in the ground. … Olive shoots can be cut off, placed in soil, and indeed they will root.15

This helps illuminate the following statement made by the Lord of the vineyard: “And, behold, the roots of the natural branches of the tree which I planted whithersoever I would are yet alive” (Jacob 5:25).

Conclusion

“In this single chapter of the Book of Mormon,” write Hess and his associates, “there are many detailed horticultural practices and procedures that were not likely known by an untrained person, and may not have been fully appreciated by professional botanists or horticulturalists at the time the Book of Mormon was translated.”16 Thus it is “hard to imagine” that whoever wrote Jacob 5 “was not personally familiar with the minute details and practices involved in raising good olives in a Mediterranean climate.”17

As an ancient Israelite prophet, Zenos would be a plausible candidate for the text’s authorship, seeing that olives were such an important crop in Israel.18 It is harder to ascribe the contents of this allegory to Joseph Smith, who “probably had little knowledge of olive trees in New York, as they will not grow in the northeastern United States.”19
