First, this important note:
Did you know the name Y'shua (Yeshua) means "Yahweh is salvation" in Hebrew? Y'shua is the only Heavenly Entity who has the Name of YHWH (Yahweh) within His own name! The angels/messengers all have the title of Elohim (God) within their names: Michael, Raphael, Gabriel....
The Name above all Names, however, is YHWH ("Yahweh"):
John 17: 11. Henceforth, I will not be in the world, and these are in the world. And I am coming to Your presence. Kadosh Father, keep them by your Name, that which you have given to me, that they may be one as We are. 12. I was with them while I was in the world. I have kept them in your Name; those whom you have given to me, I have kept. And not a man of them is lost except for the son of perdition, that the Scriptures might be fulfilled. 13. And now I come to Your presence, and these things I speak in the world that my joy may be full in them. 14. I have given to them Your Word and the world hates them because they are not of the world as I am not of the world. (Aramaic English New Testament/AENT)
 Kadosh/Set Apart means that YHWH and His Word will never change; we can put our trust in Him knowing He will keep His Word. See Unity of the Name of YHWH in Appendix.
 A very key passage. Aramaic literally reads that YHWH gave His Name to Y'shua; therefore, he has the Name of his Father within him.
 Y'shua keeps them in YHWH's name so when we call upon YHWH in Y'shua's name, we are calling on YHWH for Salvation. As the Name of YHWH is in Mashiyach, so are we to have the name of Mashiyach in us, which means that as followers of Y'shua we are to walk according to his righteousness, observe Torah and walk in the anointing of the Ruach haKodesh as Mashiyach demonstrated to us.
In view of the above, to call upon Y'shua (who was our Final SIN offering - He martyred Himself) is to call upon YHWH to save you!
(NOTE: Our use of the term "martyr" is intentional because traditional Jews love to point out that "G-d never required human sacrifice!" Well, Y'shua wasn't a "human sacrifice" because nobody "sacrificed" Him. He OFFERED, or MARTYRED himself - against which there is NO Torah command! He was a Divine "Sacrifice" (or more specifically, "offering") who willingly went to the cross/stake. As a human being, He had the choice to obey YHWH or not. As we see time and time again, He CHOSE to obey. He KNEW who He was....)
Shmaryahu Lehtimaki, Messianic Rabbi at Beit haSha’ar Messianic Fellowship Inc., posits the following:
I have always said the "words matter" and that even goes for a name. I understand and I am aware that there different ways to transliterate but there is a standard that ensures sound, grammar and vowels are properly used. There are many people who have little or no understanding of Hebrew transliterating of the name of my God and Savior's name incorrectly. This teaching is to give you an understanding of the Hebrew and transliteration involved, so you do not continue down the false sacred name movement messy-antics....
Whose name do we call out to when we want to be saved? In whose name are we sent? In whose name do we pray, preach, teach, and exercise divine authority?
Is it one of the following? Jeshua, Yeshua, Y'shua, Yeshuah, Yehshua, Yehshuah, YESHUA, YESHUAH, YEHSHUA, YEHSHUAH, Yeshouah, Y'shua, Y'shuah, Jeshu, Yeshu, Yehoshua, Yehoshuah, YHVHShua, YHVHShuah, Yhvhshua, Yhwhshua, YHWHShua, YHWHShuah, Yhvhshuah, Yhwhshuah, Yahvehshua, Yahwehshua, Yahvehshuah, Yahwehshuah, Jahshua, Jahshuah, Jashua, Jashuah, Jahoshua, Jahoshuah, Jehoshua, Jehoshuah, Yashua, Yashuah, Yahshua, Yahshuah, YAHSHUA, YAHSHUAH, YASHUA, YASHUAH, Yahushua, Yahushuah, Yahoshua, Yahoshuah, Yaohushua, YAOHUSHUA, Yaohushuah, Iahoshua, Iahoshuah, Iahushua, or Iahushuah.
Strange, isn't it? Why all the variations? Sounds like the translators were not quite sure what His Name really was, and that they did not have any original manuscript to examine. What is the correct form? There is salvation [Heb. Yeshua] in no one else; for there is no other Name under heaven that has been given among men, by which we must be saved. (Acts 4:12)
In first-century Aramaic, the Messiah's name would have been pronounced Yeshua. Somebody says, "It doesn't matter - they are all translations of the original Name." So I ask, "What right do you have to translate the Name?" A name should be the same in ALL languages. Isn't George Bush, George Bush in all languages? You don't call him Jeorge Bushes in French, Gorj Bushanoffski in Russia, or Georgeous Shrub in Australia!
Some of my readers may ask, "Does it really matter? They are just different spellings in different languages!" A name is a NAME. And if our own names are important to each one of us, and if we don't like our names being changed, why should we say, "it hardly matters" when it comes to the divine Names?
The original form of a name is the most authentic. What is the original name of "Jesus" in Hebrew and Aramaic? The claim that it was Yahshua rather than Yeshua is based largely on the work of Anson Rainey, a linguist in Israel. Dr. Rainey claims that the Masoretic Hebrew spellings Yhwshw and Yhwsh - both pointed as Yehoshua-reflect latter-day usage, when the W after the H was added to help reinforce the pronunciation of H.
In his view, originally the H simply marked the present of the vowel A, and therefore the following W would not have been present. Yeshua would then be simply a Masoretic mispronunciation of an even shorter form, likewise pronounced Yahshua originally. But this theory does not explain why, in the Masoretic Text, Yehoshua is found only in books (or citations of those books) dating from before the Babylonian Exile, why Yeshua is found only in books dating from after the Exile - nor does it explain why both names were translated as Iesous in Greek. (Iesous certainly does not derive from Zeus as some gratuitously claim).
Here again, we must look to the Jewish reading tradition for answers. The Masorete Moshe ben Asher (ca. 895AD) made clear that he and his fellow scribes did not invent the vowel-points and musical accents they transcribed; they received them-ultimately from a family of Second Temple priests called the Elders or Sons of Bathyra. Taken at face value, this testimony means that the Masoretes preserved the official pronunciation and melodic rendition of biblical Hebrew current in Second Temple times.
Moreover, we know from inscriptions that was the Hebrew and Aramaic spelling current in Yeshua's day. We also know that this name was almost always translated into Greek as Iesous. We may therefore affirm that the Masoretic pronunciation of Yeshua-is reliable. The Name Yeshua should have been transliterated into all languages exactly or very closely to the way it sounds in the original. Some transliterations are close, but some, as in English, sound far removed from the original.
Some unlearned groups spell his name Yahshua or Yahushua. This has no biblical basis and is incorrect. The Masoretic vowel tzeirei used in the name "Yeshua" in the Hebrew Bible and the Greek vowel eta in the Septuagint prove that the ancient pronunciation of the first syllable was "Ye" not "Yah". The spelling Y'shua (with an apostrophe representing a "sheva") is not valid, because it ignores the vowel tzeirei under the yod. The names "Yehoshua" and "Yeshayah" do have the sheva under the yod, but in the Masoretic text of the Bible the name "Yeshua" has a tzeirei not a sheva.
Those who insist on calling Him Yahshua are so very wrong. First, it isn't even a word in Hebrew. It isn't found once in Scripture, but the real Name of our Master, "Yeshua" is found 30 times... in the Tanakh (29 times in Hebrew and once in Aramaic). Yahshua is something that someone fabricated and it has spread throughout our circles.
You may know that it is supposed to mean "YAH" and "saves". You may have heard that "shua" means "saves". Actually, the Hebrew verb for "to save" is "yasha". The word "shua" does mean something, but what it does actually mean will shock you. The two words are related. The verb "shua" is the plural form of "yasha". A plural verb form takes the verb and intensifies it and shifts its focus to the subject. Instead of the verb describing something the subject is doing, the verb describes something that IS BEING DONE TO THE SUBJECT. That is what a Hebrew plural verb form does. This PDF document will introduce you to this concept.
What "yah-shua" actually means is not that "YAH saves" us, but that "YAH needs to be saved" or "YAH cries out for help", God forbid! It means the opposite of what our Messiah's name actually means! Do you understand the significance of that? It is blasphemy. When someone says "YAHshua" in Hebrew, they're actually saying that "YAH cries out for help". They're saying that YAH needs someone to save Him, God forbid! It is foolishness and wickedness.
I'm sure that hasatan laughs whenever he hears someone say such a blasphemous thing! I don't know the origin of this blasphemy, but I hope that you will carefully consider your involvement with it. I grew up in Orthodox faith and studied with Hebrew University and I am certain of what I am talking about. I realize that this will come as a shock to some, since so many are using this word and are convinced that it is perfectly right.
