And how exactly do you spell 'Jesus' in Hebrew?? and Greek?

Jesus

(Je′sus) [Lat. form of the Gr. I‧e‧sous′, which corresponds to the Heb. Ye‧shu′aʽ or Yehoh‧shu′aʽ

The Hebrew name for Jesus is not Yehoshua, it's Yeshua. These are two different names.

The more traditional and more exact spelling is ישוע, pronounced "Yeshua". A more recent way of spelling Jesus in Hebrew is ישו, pronounced "Yeshu". Both spellings are valid and refer to the same man, it's a matter of what you prefer.

The greek spelling is Ιησούς, pronounced "Iasus".

If you are referring to Ancient Hebrew there wouldn't be any Vowels in it. What you also have to remember is that in some languages (like the German of the Holy Roman Empire) the J is pronounced as Y.

And iamcatholic is right about ICHTHOS. ICHTHOS is what is traditionally written on the sign above Jesus' head while hanging on the cross, and it stands for "Jesus the Christ, Son of God, the Redeemer". ICHTHOS is also the Greek word for Fish, which is one reason why the Fish Symbol has been a very popular Christian symbol since the 100's A.D.

The Hebrew form of “Jesus” is “Yeshua (or perhaps Yehoshua),” which is an abbreviated form of “Jehovah-yeshua,” meaning “Jehovah is salvation.” So there it is—the name of the Father, the Supreme Being, is JEHOVAH. And how appropriate that Jesus, as Jehovah’s agent for salvation, should thus be named after his Father!

Yeshua

The original Hebrew name of Jesus is Yehoshua יהושע means "Yahweh is Salvation," "Yahweh delivers" or "Yahweh rescues."

Jesus in Greek is ΙΗΣΟΥΣ and written in the English alphabet is "IHCOYC" or "IHSOYS"

With love in Christ.

Hebrew: Yeshua שׁוּעַ

Greek: Iesous Ἰησοῦς

Ἰησοῦς. in the Greek.
