5 For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace.
6 Of the increase of his government and peace there will be no end. He will reign on David's throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and for ever. The zeal of YHWH almighty will accomplish this.
The word “El” was incorporated into Hebrew names on a regular basis: Mi'K'El = Michael = “who is like God.” Natan-I-El = Nathaniel = “Was Given to me (by) God.” It would be just as much a mistake to translate these names as meaning “this person is like God” or “God given to me” as it is to translate ElGibor as “mighty God.”
The name Elijah is composed of Eli (God) and Jah, which is short for Jahovah. The name Gabriel (גַּבְרִיאֵל) is constructed of exactly the same words as El Gibor (אֵל גִּבּוֹר). But it does not mean that the angel Gabriel is YHWH. The name Danel (not Daniel, Ezekiel 14:14, דנאל) means Judement of God. The name Emmanuel which means God [is] with us does not mean that any person named Emmanuel is the conduit of YHWH – though the writer of Matthew does some mental gymnastics to make this apply to Jesus. The name Ahijah means Brother of YHWH. There's no one who thinks that YHWH has a literal brother.
The commas in that translation are not in the original. Neither are the capitalized words.The way most Jews understand it is as follows:
“And he will be called wonderful, counselor, God-is-mighty, always father, prince of peace.”
So all you have is a Jewish Messianic prophecy listing the various names and titles which will be conferred to Messiah if/when he comes.
