Most Greek sources if not all render Jesus name as "Ἰησοῦ or Ἰησοῦς". Even the sources that others do not feel are correct for the bible. That is an incredible amount of unity. So there is a really good chance logically that his name sounded like that Greek Pronunciation.
The beginning Greek Iota Ἰ has the sound of a Y in the form of Smooth Breathing It was derived from the Phoenician letter Yodh similar to the Hebrew (י) Yod which also has the sound of a Y.
The Hebrew name for Jesus is (ישוע).
I have come in My Father’s name, and you do not receive Me; if another comes in his own name, him you will receive. (John 5:43 NKJV)
So both the Hebrew and the Greek are in agreement to the sound starting with "Y".
The Second letter in the Greek Eta η and sounds of a "Long E". So together the Greek (Ἰη) has the sound of "YE".
The Tetragrammaton is a spelling of the Father's Name as (יהוה). The Second letter is the Hebrew He (ה). So the Sound for the first Two letters (יה) Has been in much disagreement. However knowing what we know from the Greek pronunciation the Sound "YE" is possible.
The second Hebrew Letter to the Name Jesus is the Shin (ש) can carry both the sound of an "S" or a "SH". The third comparative letter in Greek is the Sigma σ and also carries the sound of the "S". So for The Name Jesus in Hebrew (יש = Yesh or Yes) in Greek (Ἰησ = Yes).
The Third letter in the Tetragrammaton is the Vav (ו) and can carry the sound of w, v, o, u. The fourth Letter again is the He (ה).
Now in the Greek after the Sigma is the two letters (οῦ). Now it is agreed that the Ancient Pronunciation for the "Hebrew Vav" can carry the sound of OU. So this leans away from the W or the V pronunciation.
The Final Hebrew letter in the Hebrew spelling for Jesus is the Ayin (ע) is usually a silent letter.
- So the Hebrew Version For Jesus is most likely (YESHOU | YESOU)
- So the Greek Version For Jesus is most likely (YESHOU | YESOU | YESOUS | YESUS)
- Making the Pronunciation for the Name of the Father most Likely (YEOU)
So literally if the "S" represents Salvation, Then the Salvation came "IN" the Father's Name also literally as "YESOU". Cool huh ^^
