From everything I have ever read, I think it was Jeshua, pronounce jeh’-shoe-ah,
His name is Yeshua in the Aramaic.
You’re correct, partly. I believe the “Jesus” was the Greek Translation of the Hebrew name “Yeshua.” - “God Saves.”
There are several references in the KJV NT to the OT Joshua but they use the Greek name Jesus. It could get confusing.
Sorry, it wasn't. Loo it up in any Hebrew or Greek lexicon, or int the Hebrew and Greek dictionaries in the back of Strong's Exhaustive Concordance of the King James Version. In the Old Testament, the Hebrew is "yeh-ho-shoo'-ah" or "yeh-ho-shoo'-ah" and likely the same in Aramaic. But in Greek it is "ee-ay-sooce'" of which Strong says:
Of Hebrew origin [H3091]; Jesus (that is, Jehoshua pronounced ), the name of our Lord and two (three) other Israelites: - Jesus.where thew J issounded as it would be in German, with "J" sounding like "ee" as in the German word "Jah" which sounds to us in our alphabet "eeah" which we would spell as "Yah."
