From the Old Testament we have Strong's H3444 and it occurs 77 times in the KJV.
ישׁוּעה
yeshû‛âh
yesh-oo’-aw
Feminine passive participle of H3467; something saved, that is, (abstractly) deliverance; hence aid, victory, prosperity: - deliverance, health, help (-ing), salvation, save, saving (health), welfare.
The name "Jesus" is a transliteration which comes from the name we know as "Joshua" or Yehoshua. The letter "J" was put into use about 500 years ago.
Or
jesus is simply how you say his name in the English language rather than Hebrew …..
“Now when this was noised abroad, the multitude came together, and were confounded, because
that every man heard them speak in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilæans? And
how hear we every man in our own tongue, wherein we were born? Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judæa, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God. And they were all amazed, and were in doubt, saying one to another, What meaneth this?”
Acts 2:6-12 KJV
would be odd if anyone needed to learn a foreign language to believe in him
