Exodus 3:14: “Ehyeh-Asher-Ehyeh” means: “to be, to exist—the `I AM’”. From page 59, a footnote in The Scriptures: “The Hebrew text (of Exodus 3:14-15) reads `eyeh asher eyeh’. The word `eyeh’ being derived from` hayah’, which means: `to be, to exist’”.
Yet it is believed by some that His whole Name is included in Exodus 3:15 and that Yahuweh is the shortened form of His whole Name. This is very possible because of His identification with the three that He made covenant with: Abraham, Isaac and Jacob”. Exodus 3:15: “Thus you shall say to the children of Israel, `Yahuweh Elohim of your fathers, the Elohim of Abraham, the Elohim of Yitshak, and the Elohim of Yaaqob has sent Me to you’. This is My Name forever and this is My memorial to all generations’”.
His basic Name means: “I am the eternal, existing One—the One who breathes”. The “hawah” or “haweh” means to breath.
From the article “The Name of Elohim” by Ruvan Ben Gershom, page 3: “In the Holy Scriptures, this Name is used when discussing Elohim’s relation with human beings, and when emphasizing His qualities of loving kindness and mercy. It is frequently shortened to Yah (Yod-Heh), Yahu or Yaho, …especially when used in combination with names or phrases, as in Yahoshua, being Hebrew for Joshua. HalleluYah is `praise Yahuweh’”
However, the spelling and pronunciation of Yahweh and Yahshua is valid and so acknowledged by most Hebrew/Biblical scholars. The importance is to get the Yah in the Name—the: I AM. Note: More recently, most scholars realize that the third Hebrew letter of the Father’s Name, is a “w” sound, not a “v” sound—a “waw and not a vav”. In my studies, I have come to believe that the best sound-pronunciation of the Son’s Name is Yahoshua—the “u” breath sound can also take on an “o” sound—translated as Joshua in the English language. I write the “u” also in the Son’s Name for mainly uniformity with the Father’s Name. The name “Yahoshua” is also confirmed by Jewish archeologists, and is the spelling for “Joshua” in Hebrew. In both cases, the emphasis is on the “Yah” sound. In the book Joshua’s Altar, by secular archeologist and author, Milt Machlin, he says, on page 127: “Joshua’s original name in Hebrew was Hoshea. It was changed to Yehoshua—Joshua in English by Moses. Yehoshua is the Hebrew name of Jesus also. In Hebrew it means `God is salvation’. `Jesus’ is…from the Greek Iesous.” (Of course Mr. Machlin would not say “Yahweh is salvation”, because even though he is a secular Jew, he still has the cultural fear of using the real Name of the Father and thus maybe offending Him and his fellow Jews).
