David, in the Book of Mormon context, is referred to not as a primary character within the narrative but as a historical figure from the ancient kingdom of Israel, whose lineage and actions bear significance to the Nephite people. Mentioned explicitly in relation to the prophecies of Isaiah, the “house of David” signifies both the royal lineage and the political entity of Judah, under the threat of a confederacy between Syria and Ephraim (2 Nephi 17:2). The stability and continuance of David’s throne are underscored in the assurance that of the “increase of government and peace there is no end, upon the throne of David” (2 Nephi 19:7), a prophecy that alludes to the eternal reign of Christ, who is biblically acknowledged as a descendant of David.
However, David’s practices with regard to marriage are invoked critically by Jacob, a Nephite prophet, who admonishes his people for their unauthorized practice of plural marriage. Jacob condemns these practices by equating them with the “abominable” actions of David and Solomon concerning their many wives and concubines (Jacob 1:15; 2:23-24). This denunciation reflects a theological stance against certain behaviors of these ancient Israelite kings, despite their significant roles in the religious heritage shared by the Nephites. Jacob’s rebuke emphasizes a distinction between cultural or historical precedents and divine commandments, urging adherence to the latter. David’s mention in the Book of Mormon, therefore, serves a dual purpose: as an anchor for messianic prophecy and as an example in admonitory lessons regarding righteous conduct.
