1. In Isaiah 9:6 the two names are the names of King Hezekiah, the greatest of the Jewish kings. It is much better translated, "A wonderful counselor is the mighty God," and "The everlasting father is the Prince of Peace." Jews often take names that describe God.
2. I'm not quite educated enough to answer you on the "He would be cut off" question, but I seem to have a vague memory that Rashi says it refers to King Agrippa. In any case, I don't know why you think it means crucified. That's kind of a giant leap that is not in the text. Perhaps
@Jewjitzu or
@Harel13 might have something to add.
Daniel 9:24-27
New King James Version
24 “Seventy weeks are determined
For your people and for your holy city,
To finish the transgression, To make an end of sins,
To make reconciliation for iniquity,
To bring in everlasting righteousness,
To seal up vision and prophecy,
And to anoint the Most Holy.
25 “Know therefore and understand,
That from the going forth of the command ( from King Artaxerxes to Nehemiah in Nehemiah chapter two - about 444 BC )
To restore and build Jerusalem
Until
Messiah ( Jesus ) the Prince,
There shall be seven weeks and sixty-two weeks;
The street shall be built again, and the wall,
Even in troublesome times.
26 “And after the sixty-two weeks
Messiah ( Jesus ) shall be
cut off (
Crucified ), but not for Himself;
And the people of the prince who is to come
Shall destroy the city and the sanctuary.
The end of it
shall be with a flood,
And till the end of the war desolations are determined.
27 Then he shall confirm a covenant with many for one week;
But in the middle of the week
He shall bring an end to sacrifice and offering.
And on the wing of abominations shall be one who makes desolate,
Even until the consummation, which is determined,
Is poured out on the desolate.” --------------------------------------7 sevens & 62 sevens = 69 sevens of prophetic years = 476 solar years! Go forward from 444BC and you get 32 AD in Nissan ( March/April ) - the crucifixion date! It is actually Nissan of 33 AD since there is no ZERO year between 1BC and 1 AD!
