Jehovah Is the Name of the Premortal Jesus Christ
Joseph Smith Translation, Exodus 6:3
3 And I appeared unto Abraham, unto Isaac, and unto Jacob. I am the Lord God Almighty; the Lord JEHOVAH. And was not my name known unto them?
President Dallin H. Oaks said:
“The scriptures are replete with declarations that the name of Jesus Christ is ‘the only name which shall be given under heaven, whereby salvation shall come unto the children of men’ [Moses 6:52; see also Acts 4:12; 2 Nephi 25:20; 31:21; Mosiah 3:17].
“The Bible has hundreds of references to the name of God, a sacred word which usually refers to God the Father, or Elohim [see Genesis 1:1; John 3:16]. The ancient prophets also knew and revered the name of Jehovah, the Holy One of Israel, Jesus Christ, whom the Bible usually refers to as the Lord [see JST, Exodus 6:3; Abraham 1:16; 2:8; Ether 3:1–28; Isaiah 43:3].
“These names were so sacred that the children of Israel were repeatedly commanded not to profane the holy name of their God [see Leviticus 18:21; 19:12; 20:3; 21:6]. One who blasphemed the name of the Lord was commanded to be put to death by stoning [see Leviticus 24:16].”
