If Moses and all other Israelite prophets foretold of the Messiah as a prophet besides Isaiah 9:6 then ?

If Moses and all other Israelite prophets foretold of the Messiah as a prophet and prince according to Deuteronomy 18:18, Daniel 7:13-14 and Ezekiel 43 besides Isaiah 9:6 then can we conclude that Isaiah 9:6 was altered when the Bible was translated into it's English which the translators added the concept of the Messiah becoming God in Isaiah 9:6. The reason I say this is because Isaiah 9:6 is the only verse in the whole Old Testament that refers to the Messiah as a Mighty God. It doesn't even run parallel to the prophecy of the Messiah according to the other prophecies I mentioned above. I have only came to a conclusion that Isaiah 9:6 is altered and that the only correct words in that verse is Prince.
