Lip and tongue and throat and mouth movements save no one. Letters, symbols, figures and numbers save no one.
Jesus Christ the King of Israel, and the incarnate Son of God saves.
Acts 4:12 Neither is there salvation in any other. For there is no other name under heaven given to men, whereby we must be saved.
Now, does the name Yeshua save people? It means "Saviour." The name Yeshua saves no one. Yeshua Himself saves; because in Hebrew, "in/by the name of" means 'by' or 'into' or 'by the authority of.'
Ecclesiastes 6:4 For he came in vain, and goeth to darkness, and his name shall be wholly forgotten.
Here, "his name" means "he himself." "His reputation." His name might be forgotten as well, but that's not what is meant by "his name shall be forgotten." Here it means he himself, the person, the identity, the fame of him, will be forgotten, or not committed to record.
As such, whether you say Jesus like Yesous (Greek) (per the New Testament) or Yeshua (Hebrew) or Hesus (Spanish), Gesu, (Italian) etc. you are still referencing one name only, pronounced according to the region which to a greater or lesser degree appropriated the name in its language.
The applies to Peter. Also known as Keefa (כפא), Petros (Πετρος), Pierre, etc. And any other name (e.g. Mathityahu, מתתיהו also known as Matthew).
In Semitic culture, one's name is their identity or authority as personified as distinct from from, but in direct reference to, themselves.
Revelation 2:3 And thou hast patience, and hast endured for my name, and hast not fainted.
Quite clearly He means they have suffered willingly on account of their witness of Him, not for four letters (Hebrew), or six letters (Greek).
Revelation 3:1 And to the angel of the church of Sardis, write: These things saith he, that hath the seven spirits of God, and the seven stars: I know thy works, that thou hast the name of being alive: and thou art dead.
Here, name means reputation.
Matthew 28:19 Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.
One name incorporates three Persons who go by different names. So name here means the nature or identity or spirit of the one God. (In Greek it's clear because the single word "into" covers each Person as having only one name.)
In other words, name only means the spelling or sound in English and some other European languages. In Hebrew and Semitic culture, the name is your identity or person, not the word that represents you.
