According to John Welch, Jesus was personally known to many Book of Mormon prophets, for he appeared to several, including Lehi (1 Nephi 1:9), Nephi (2 Nephi 11:2), Jacob (2 Nephi 2:4; 11:3), Mormon (Mormon 1:15), the brother of Jared (Ether 3:14), and Moroni (Ether 12:39), as well as to the multitude in 3 Nephi. Others like Benjamin, Alma, Amulek, and Samuel the Lamanite saw "the angel of the Lord" (Mosiah 4:1; 27:11; Alma 10:7; Helaman 13:7), which may be a euphemism for seeing the Lord himself (for example, it is difficult to distinguish between "the angel of the Lord" and Jehovah in Genesis 16:7-11; 22:11-15; Exodus 3:2; and Judges 2:1-4). Thus, their teachings and testimonies about Jesus are based on firsthand knowledge and acquaintance. [John W. Welch, "Ten Testimonies of Jesus Christ from the Book of Mormon," F.A.R.M.S., 1994, p. 1]
