Alma 37:23

It's interesting to note that in the 1835 Doctrines and Covenants section 82, Joseph Smith is referred to as "my servant Gazelam." When certain revelations were published in the 1835 edition of the Doctrine and Covenants, code names were substituted to protect the identities of individuals and locations. These pseudonyms were used in sections 77, 81, 89, 93, 101, and 102.

Once the "code names" became unnecessary, they were dropped in favor of the actual individuals. Examples include: Ahashdah = Newel K. Whitney, Alam = Edward Partridge,
Gazelam = Joseph Smith Jr., Horah = John Whitmer, and Olihah = Oliver Cowdery.

"With reference to the name Gazelam, it is interesting to note that Alma in directing Helaman to preserve both the Urim and Thummim and the plates containing the Book of Ether, says that such record will be brought to light by the Lord’s servant Gazelem, who will use “a stone” in his translation work. (Alma 37:21-23.) It may be that Gazelem is a variant spelling of Gazelam and that Alma’s reference is to the Prophet Joseph Smith who did in fact bring forth part at least of the Ether record. Or it could be that the name Gazelem (Gazelam) is a title having to do with power to translate ancient records and that Alma’s reference was to some Nephite prophet who brought the Book of Ether to light in the golden era of Nephite history." -Mormon Doctrine, 2d ed. [1966], p.307.

"Is Gazelem the seer stone or the servant? It is difficult to tell from the passage and depends very much on the placement of a comma in the sentence. Perhaps it could refer to both. It is interesting to note that when Jesus called Simon Peter to the ministry he said: “Thou art Simon the son of Jona: thou shalt be called Cephas, which is, by interpretation, a seer, or a stone” (JST, John 1:42). Though this name or title of Gazelem may be used in regard to any seer who utilizes seer stones, it seems in this instance to be a direct reference to Joseph Smith the Prophet." -Doctrinal Commentary on the Book of Mormon, 4 vols.[1991], 3:.278 Joseph Fielding McConkie and Robert L. Millet.

This verse appears to support the concept of the seer stone used by Joseph Smith in receiving revelation during the translation of the Book of Mormon.

The October 2015 issue of the The Church of Jesus Christ of Latter-day Saints magazine Ensign includes a photograph of the seer stone and explains, "In fact, historical evidence shows that in addition to the two seer stones known as 'interpreters,' Joseph Smith used at least one other seer stone in translating the Book of Mormon, often placing it into a hat in order to block out light. According to Joseph's contemporaries, he did this in order to better view the words on the stone.... according to Martin Harris, Joseph also used one of his seer stones for convenience during the Book of Mormon translation. Other sources corroborate Joseph's changing translation instruments." —“Joseph the Seer,” Ensign, October 2015, 53.

“In frontier America, seer stones or “peep stones” were commonly used by lost object finders, people engaged in the widespread practice of lost treasure digging, and sometimes by people seeking to uncover the kind of truths we might call a private or police detective for today. It is unclear how much of this kind of activity Joseph Smith was involved in, except for water divining and treasure digging, which are widely attested.” -Eric A. Eliason, BYU Studies Quarterly, Vol.55, No.1, 2016.
