Specifics are important, but so is consistency in the prophetic message. The use of repeated words and phrases is not careless, but meaningful.
Which is why I pointed out the repeated use of the words which indicate that the subject is the nation. You didn;t really address that. Instead you generalized "context" to include everything.
Take, for example, the anointing of a man with the Spirit of God. In lsaiah, there is repetition of the idea of the Spirit resting upon a man.
Ne careful though -- the use of words is not careless, but you just replaced "anointing" with "resting".
Torah Jews like to say that there are many kings and priests anointed by God.
Well, actually, the Torah says that.
Yet the imperfect all point to the perfect, and the perfect one is Christ.
That means nothing. The texts says what it says. Your decision about what something points to is pure invention.
In Isaiah 61, the Spirit of God rests upon a man. Torah Jews refuse to accept that this man is Christ, despite a consistent message throughout lsaiah.
Well, 61 begins in the first person who has had the spirit of prophecy rest on him (elsewhere, and I can give you verses, the spirit resting is a reference to prophecy and prophets are called "anointed ones"). And since this text is written from the first person of Isaiah, it is weird to insist that suddenly and out of no where, the first person perspective is that of an external character who is never actually named.
Isaiah 11:1 is, l hope we agree, unquestionably about the king Messiah.
That is one way to understand this verse, yes. Not the only way, but one of them.
Isaiah 11:2 tells us that that the spirit of the LORD 'shall rest upon him'.
If you subscribe to the rabbinic understanding of biblical Hebrew.
Isaiah 42:1, again, tells us about the king Messiah. 'I have put my spirit upon him', says God.
No it doesn't -- the subject is understood either to be the speaker (Isaiah, the prophet, upon whom the spirit of prophecy was given) or about the nation of Israel (compare the word "chosen" to Ps 135:4, and the identification of the servant as the nation in Is 45:4). So you jump to a conclusion erroneously and that allows you to say "again" when that isn't the case if you look at the words.
Isaiah 59:21. Again, referring to the king Messiah. 'My Spirit that is upon thee'.
Again, no. The reference could be to the prophet Isaiah, or to the people (cf Joel 3:1). Look at the words.
Then we come to lsaiah 61:1. The king Messiah speaks. 'The Spirit of the Lord GOD is upon me'.
No, he doesn't. That's your invention at work, again.
The Spirit of the Lord is determined to rest upon his chosen. The chosen one is the Messiah. Yet, remarkably, Torah Jews ignore the consistency of lsaiah's message and suggest that it's lsaiah himself claiming the anointing!
When you ignore the words and phrases, the use of "anointed" to refer to prophets, the idea that the spirit of prophecy rested on this prophet and, in future, on all Israel (who are called his chosen) and when you need to include a completely external character, you end up with a total mish mash. Remember, "The use of repeated words and phrases is not careless, but meaningful" so you should pay attention to it.
And you haven't.
