The terms endow, endowed, and endowment—as well as endued and enduement—were used to describe the bestowal of spiritual blessings upon the Latter-day Saints. In common usage, these terms meant essentially the same thing: to clothe, to put on, to furnish, or to supply with.1 In revelations in 1831, Latter-day Saints were promised an endowment “with power from on high,” and by 1833 the promises were associated with the House of the Lord, then under construction in Kirtland, Ohio. In one reference, the promises were made analogous to the New Testament instruction to the apostles that they should tarry at Jerusalem until they were “endued with power from on high.”2 Many Latter-day Saints considered the outpouring of spiritual power, including speaking in tongues, visions, and prophesying, that they experienced in Kirtland in March 1836 to be their endowment with power.3 Church members later referred to a specific temple ordinance introduced in 1842 in Nauvoo, Illinois, as an endowment.4
