Looking at the meaning of the name Elijah. Eli-Yah

êl - Shortened from H352; strength; as adjective mighty; especially the Almighty
'ayil ah'-yil From the same as H193; properly strength; hence anything strong; specifically a chief
'ûl ool From an unused root meaning to twist, that is, (by implication) be strong; the body (as being rolled together) also powerful: - mighty, strength.

That also begins to form the meaning of the Waw Y Righteous Branch ! (Zech 6)

From H1961; (the) self Existent or eternal;
hâyâh haw-yaw' A primitive root (compare H1933); to exist, that is, be or become, come to pass (always emphatic, and not a mere copula or auxiliary): - beacon, X altogether, be (-come, accomplished, committed, like), break, cause, come (to pass), continue, do, faint, fall, + follow, happen, X have, last, pertain, quit (one-) self, require, X use.

Looking at the Meaning of the name Moses.

môsheh mo-sheh' From H4871; drawing out (of the water), that is, rescued; Mosheh, the Israelitish lawgiver: - Moses.
mâshâh maw-shaw' A primitive root; to pull out (literally or figuratively): - draw (out).

Looking at the Meaning of Torah
tôrâh tôrâh to-raw', to-raw' From H3384; a precept or statute,
yârâh yârâ' yaw-raw', yaw-raw' A primitive root; properly to flow as water (that is, to rain); transitively to lay or throw (especially an arrow, that is, to shoot); figuratively to point out (as if by aiming the finger), to teach: - (+) archer, cast, direct, inform, instruct, lay, shew, shoot, teach (-er, -ing), through.

From Ancient Hebrew studies the meaning of Torah becomes the same as the Path of Life - as in teaching instructions, an arrow shot from the bow, sharp, of the T taw To Remember that It Is Finished, Y waw The Secure Absolute Righteous Branch, R resh the Beginning Chief Head Rosh Pina of the, H hey Revelation by the Breath of Life/Spirit. The Way, the Truth, and the Life.

Torah - Moses - Elijah - Prophet (Meanings)
(The Path of Life of Y the Head Stone is the Breath of Life Bringing Water from the Well of Salvation to rescue his people and is the same Almighty YHWH the true Prophet.) Deu 18.

We know who is Y from Zech 6. The Righteous Branch of the name of YHWH.

I believe this is Messiah Yah'shua who comes in the Spirit of Elijah and in the Spirit of Moses (per pro the Transfiguration) since He is the Rosh (Head) of both the Torah and the Prophets.

Is this "Elijah" who we let come in at Passover when we celebrate the Living Passover Lamb of salvation?
Revelation 3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. 21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.

Yes, we couldnt mistake our Rosh Pina!
And could we also say he is the light of Moses and Elijah... John, ... and we too!

And we see other scriptures to ponder on as well to lift up our Messiah! Isn't he just as he said!

YHWH Elohim by His Power of His Outstretched Arm made the men we see in scriptures, even we, and all that exists, and gave us the meanings of our Life, and is showing us that he is right in the very heart of everything, the founder and maker, who became as a living breathing man, our savior who wrote Torah by His Life to the Taw!, whom we must take at his word and pay heed to his sayings!
