From Yesha’:

There is another Psalm which depicts Yahushua’s gift, emphasizing His Soul rather than His sacrifice. It is Psalm 88. It begins with the three most important names in creation: “Yahuweh ‘Elohiym Yashuw’ah.” (Psalm 88:1) Yahuweh is ‘Elohiym/God as is Yahushua, the diminished manifestation of Yahuweh in human form. In the next chapter, “Ga’al-Redemption,” we will study the Hebrew root of Yashuw’ah in depth because Yasha’yah/Isaiah uses the Messiah’s name frequently in his prophetic introduction to the Suffering Servant.

From Ga’al: Speaking of the Messiah’s ruling advent, Yasha’yah reveals: “In His (hiy) day (yowm) they will know that I Am He (hiy) who speaks (dabar – declares, converses, warns, promises, and says) ‘For (kiy) behold, look and see, here I Am (hinneh).’” (Isaiah 52:6) With the Yahudim, this will not occur in mass until the Messiah returns on Day of Atonement in 2033. There will be but 5 days left on mankind’s 6,000 year (2,191,500 day) history—a mere five seconds on a twenty-four hour clock.

You may wonder why I am certain that Yahuweh is associating “knowing His name” and His name’s influence on “being included in His family” with the return of the Messiah. It’s because He said so. “How lovely (na’ah – beautiful and befitting, attractively and appropriately adorned) upon the mountains are the feet of the One who brings and embodies (basar – bears and announces news of) restoration and renewal (shalowm – a completely sound, satisfied and favorable state; the blessings of loving kindness, friendship, and relationship; the granting of peace, safety, salvation, and well-being), the One who announces and proclaims good things (towb – that which is beneficial and agreeable, prosperous and valuable) who hears (shama’) Yahushua (Yashuw’ah) and says to (‘amar – speaks to and answers) Zion, ‘Your ‘Elohiym reigns!’” (Isaiah 52:7)

Also from Ga’al: The next verse is a sermon in itself. It confirms that Yahuweh can and will manifest Himself in a physical form who can be seen by all. The form is human. In Human form Yahuweh is Yahushua. “Yahuweh has bared (chasaph – uncovered and revealed) His Set-Apart (Qodesh) sacrificial Lamb (zarow’a) in the eyes of all Gentile nations (Gowy). And without exception, all the earth will see Yahushua (Yashuw’ah), Elohiym.” (Yasha’yah/Isaiah 52:10)

Translators are wont to say “Yashuw’ah (יְשׁוּעָה)” is “salvation,” calling Yashuw’ah a passive participle of yasha’ (יֵשַׁע). They do not explain why yasha’, which is already a masculine noun meaning “salvation” needs to be altered with the addition of two additional letters to remain as “salvation.” They don’t explain the unique coincidence that the additional letters serve to unify Yahuweh’s name with the Savior’s. If God were to create a compound title that combines His name and His mission, Yahuweh (יהוה) and Salvation (יֵשַׁע), it would be rendered: Yashuw’ah (יְשׁוּעָה). While I transliterate the sound of the Devine name with the English letters “Yahushua” for clarity and simplicity, phonetically, “Yashuw’ah” is identical to Yahushua.

In context, Isaiah 52:10 is destroyed when “Yashuw’ah,” the tangible and visible human manifestation of Yahuweh, is replaced by an intangible and invisible concept, “salvation.” Everything we have just read tells us that everyone will see Yahushua with their eyes. The startling reality that sobers the Yahudim, causing them to cry out Yahushua’s name and sing, “God is One Unity,” is the realization that Yashuw’ah is Messiah, Yahuweh manifest in human form.

It bears repeating: “In His day they will know that I Am He who says, ‘For behold, look and see, here I Am.’ So therefore, this is right, just, honest, verifiable, correct, and true: My family shall know My name. How lovely and appropriately adorned upon the mountains are the feet of the One who brings and embodies restoration and renewal, the One who announces and proclaims good things regarding that which is beneficial and agreeable, who hears, ‘Yashuw’ah’ and says to Zion, ‘Your Elohiym reigns!’ Listen, your watchmen lift up their voices and shout for joy, ‘Yachdiy’el,’ they sing. For in plain sight they will look upon, inspect, and observe with their own eyes Yahuweh’s return to Zion with mercy. Burst forth, sober up and shout: ‘Yachdiy’el,’ desolated Yaruwshalaim. Yahuweh has shown compassion and comforted His repentive and changed family, and He has redeemed and restored Yaruwshalaim. Yahuweh has bared and revealed His Set-Apart sacrificial Lamb in the eyes of all Gentiles. And without exception, all the earth will see Yashuw’ah, Elohiym.” (Yasha’yah/Isaiah 52:6-10)
