Book of Mormon Word Usage:
"Seal You His"
The verb to seal occurs some 34 times in the Book of Mormon.1 In most of these instances the verb takes (is followed by) a direct object referring to such things as the law, a book, records, words, an account, an epistle, an interpretation, revelation, the truth, and the stone interpreters.2 Twice, however, the verb to seal takes a person as a direct object that is qualified by a possessive pronoun:
Therefore, I would that ye should be steadfast and immovable, always abounding in good works, that Christ, the Lord God Omnipotent, may seal you his, that you may be brought to heaven, that ye may have everlasting salvation and eternal life, through the wisdom, and power, and justice, and mercy of him who created all things, in heaven and in earth, who is God above all. (Mosiah 5:15; emphasis added)
For behold, if ye have procrastinated the day of your repentance even until death, behold, ye have become subjected to the spirit of the devil, and he doth seal you his; therefore, the Spirit of the Lord hath withdrawn from you, and hath no place in you, and the devil hath all power over you; and this is the final state of the wicked. (Alma 34:35; emphasis added)
While use of the term to seal to mean “to mark as one’s property, and secure from danger”3 was known in Joseph Smith’s day, it was not usually used of persons. What, then, are we to make of the expression “seal you his” in the Book of Mormon? Hebrew seals from before the Babylonian exile (and thus in use during Lehi’s time) provide helpful insight. Many of those seals contain a formulaic inscription reading “belonging to,” followed by the owner’s name.4 To seal a document or an object, a person would wrap string or twine around it, place a daub of mud on the knot, and press the seal into the mud. Affixing this sort of seal marked the object as the possession of the person in whose name it was sealed.
It is this cultural milieu that underlies the seemingly peculiar usage in the Book of Mormon and clarifies its meaning: our actions allow either Christ or the devil to place his seal on us to indicate to whom we belong.
