"Jehovah" is not a name. It is the three Hebrew letters that spell "Yaheh", the Hebrew name for God. It was against Hebrew law to utter the name of God so in conversation, Hebrews would spell it out, hence the term "Jehovah"<br />
Jesus's real name in Aramaic, the language he spoke was, Yeshua.
So, wait, you knew Jesus personally but didn't know his name? How's that work?
