Jesus' birth name is Aramaic or Hebrew, Yeshua. Transliterated into Greek, Jodh becomes Iota (ee sound); eh becomes epsilon (eh sound); shin becomes sigma (Greek has no sh sound, only the hiis of our s); vav (oo sound) becomes a dphthong omicron-upsilon (sounds like oo). However, the Greek words are inflected to show the case of the noun as used in the sentence, so a sigma at the end signifies the nominative case, and replaces the sound "ah" (letter aleph? vowel point?). thus we have "Iesous"; but Germans turn the Yah sound into a J, as in "Ja!" meaning yes but sounding like Yah. So willy-nilly we adopt the J also, but sound it like "dsh". God's son's name is Joshua, with the J sounding "ee, not "dzh".
