I appreciate your acknowledgement.
It's a start toward integrity!
You assume the seventy are sevens, but they're not. Per Young, Keil, & Kliefoth (per Walvoord) the diction is NOT in the usual Concise Feminine Gender text, -- it's in the unusual INCONCISE Masculine Gender text, which is
ONLY found in the 9th Chapter of Daniel, and nowhere else in Scripture. (I tell people it's analogous to going for a ride in a "
cool car", where the invited grabs his hat, coat, scarf, & gloves. -- It's not a concise depressed thermal gradient. It's the inconcise "
slang".)
So the FIRST thing we know is that the 70 ≠ 490. And of course,
9:2 says "
years" and that we can find the confirmation "
in the books" -- which is NOT the Book of Jeremiah, but instead using the "
perceived" Solomon Wisdom (1 Kings 3) the validation is in the Prophetic Psalms, -- all in compliance with the angel's instructions in
12:4 & 9.
And although you DID acknowledge one mistake, I don't think you're up to correcting your "70 week" mistake.
