Hellenistic culture are fond to worship human looking god and son of god. If you notice the so called prophecies cannot be found in one passage.
What they did is quote one verse 7:14 but did not quote the whole story. Before the kid reaches the age of moral discrimination, 12 years old at the latest, the kingdoms of Israel and Damascus will be deserted.
And then they look for other traits that can be linked with their human god in other books.
then suddenly they found verse 9:6 that seem adaptable to Pauline doctrine of human god, but then 9:6 only says about titles given to the ruler.
King Melchizedek too has titles that are equal to God himself. But that doesnt make King Melchizedek = God.
And the same applies for the messiah, in fact all the miracles carried out by the messiah were due to the permission given by Yhwh after commanding Holy Spirit to strengthen the messiah by residing in his body.
If one reads Daniel 7:13-14 its just a normal statement about "son of man". Not son of god.
And Yhwh use the phrase "son of man" in Numbers 23:19 to show that divinity cant be relate to phrase "son of man"
