Ok, for one thing, let’s not care for the opinions of those who are critics of the Bible, because they’re not G-d, and they have a baggage of biases which they carry with them. I want to explain something to you, and that’s the history of this goofy theory, because Isaiah wrote all 66 chapters, and your facts are not based on some linguistic study, they’re based on atheists, who don’t believe in the G-d of Israel. For example, when Isaiah says in Ch. 45:1 that Cyrus, who lived a century later, would be king, he meant it (see 44:28 for the fulfillment). My point? Of course an atheist who doesn’t believe in the Bible is going to say Isaiah couldn’t have possibly wrote that, but what do you think their going to say!!!
Now, as you’ll recall, this theory was first purposed by, oh - not by Ibn Ezra, give me a break - but by Baruch Spinoza (1632-1677 CE). Later, it received growing pains and the theory was redeveloped a few times by some other guys, the most famous being Dr. Julius Wellhausen. It was him, who, in 1895, selected the dates to J, E, D, P, and R, even though he conveniently forgot to compare that data with other ancient Hebraic sources to see if they matched up. In other words, it was more along the lines of a wild, and totally uneducated, guess, and perhaps the notion of a redactor suited him well since it paralleled German unification and culture and served as a sort of metaphor for what he’d like to have seen happen with his own nation. Moreover, Wellhausen’s agenda was to pattern Judaism after Christianity, being that there were now also four “contradictory” accounts of a recorded event (i.e., Tanakh). Hence, according to the secular world, the Hebrew Bible became nothing more than a man-made document, a laughingstock, evolving over time, and full with all its fabricated flaws. This, of course, it totally false, and the following data of mine will prove it.
