Jehovah
For behold, it came to pass that the Lord spake unto my father, yea, even in a dream, and said unto him: Blessed art thou Lehi, because of the things which thou hast done; and because thou hast been faithful and declared unto this people the things which I commanded thee, behold, they seek to take away thy life. 1 Nephi 2:1–2
The Lord, Jehovah, speaks to Lehi in a dream, blesses him, and commands him to take his family into the wilderness. In Latter-day Saint understanding, the premortal Christ is the one guiding Lehi's family.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
