The covenant or proper name of the God of Israel. It denotes "the eternal I AM" (Ex. 3: 14; John 8: 58). Jehovah is the premortal Jesus Christ and came to earth as a son of Mary (Mosiah 3: 8; 15: 1; 3 Ne. 15: 1-5). Usually, when the word Lord appears in the Old Testament, it means Jehovah.

Jehovah is Christ: Jehovah was known to the ancient prophets (Ex. 6: 3; Abr. 1: 16). The Apostle Paul taught that Christ was the Jehovah of the Old Testament (Ex. 17: 6; 1 Cor. 10: 1-4). The brother of Jared in the Book of Mormon saw the premortal Christ and worshiped him (Ether 3: 13-15). Moroni also called Christ Jehovah (Moro. 10: 34). At the Kirtland Temple, Joseph Smith and Oliver Cowdery saw the resurrected Jehovah (D&C 110: 3-4).
