A Dictionary of the Book of Mormon/Lehi, the son of Helaman
LEHI, THE SON OF HELAMAN. Were we to attempt to sketch the life of Lehi, we should simply have to repeat the most striking features of that of his elder brother, Nephi. In their labors, journeyings, ministrations, etc., they seem to have always been together. Like Samuel of old, in their childhood they "began to grow up unto the Lord," and in riper years they lived to His glory. In speaking of the exalted character of Nephi, the historian adds, "And behold, Lehi, his brother, was not a whit behind him as to things pertaining to righteousness.”
The date of Lehi's birth is not recorded. In the year B. C. 44, the fact that Helaman had two sons, named Nephi and Lehi, is mentioned; but at that time they must have grown to manhood, as their public labors began shortly after. Lehi accompanied his brother in his extended labors throughout the lands of the Nephites; he was with him in prison among the Lamanites, in the city of Lehi-Nephi, at the time of the great manifestation of God's power, and the conversion of the greater part of that people to the service of the true God; he went with Nephi to the northern continent, and labored there several years. Again we hear of them (B. C. 13) still laboring in the might of Jehovah and the powers of the priesthood for the salvation of the souls of men. After this we lose sight of Lehi, the date, the place, or circumstances of his death are not stated.
