Here’s a good explanation of the name Jesus:
“Jesus is actually an English corruption of the Latin, Iesus (Latin did not have a J).
Iesus, comes from the Greek Iesous (Greek was the language of the New Testament).
Iesous itself is a Greek transliteration of Aramaic, Yeshua (Jesus’s mother tongue was Aramaic).
The aramaic form of the name is a derivation of the old Hebrew name Yashua.
Yeshua – was a very common name in the Roman province of Judaea at the time.
