Jehovah
Jehovah — the eternal I AM, the premortal Jesus Christ; 'everlasting strength' is literally 'Rock of Ages'
Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. Isaiah 26:3–4
The name JEHOVAH appears in the text itself. Perfect peace comes to the one whose mind rests on Jehovah, the premortal Jesus Christ, who is the Rock of Ages and everlasting strength.
How we know: the verse itself names Him · the chapter heading names Him · a footnote points to Him · a Church study aid lists it
- the same title in Isaiah 12:2 — the LORD JEHOVAH is my strength and my song
- the same title in D&C 110:3-4 — the voice of Jehovah: I am he who liveth, I am he who was slain
- the same title in Moroni 10:34 — the great Jehovah, the Eternal Judge
