Douggg, I do not intend to get into a lengthy discussion with you over those issues, because they have already been covered in other Jewish presentations on Daniel 9.  As to the Masoretic markings, they are from around the 9th & 10th century CE.  So what?  The textual syntax, context, and relationship to other texts in the Hebrew Bible help determine the structure as well, and the trope markings just facilitate it and make it much easier.

Our raison d'être:

WHOSOEVER DESTROYS A SINGLE SOUL OF ISRAEL, SCRIPTURE IMPUTES [GUILT] TO HIM AS THOUGH HE HAD DESTROYED A COMPLETE WORLD; AND WHOSOEVER PRESERVES A SINGLE SOUL OF ISRAEL, SCRIPTURE ASCRIBES [MERIT] TO HIM AS THOUGH HE HAD PRESERVED A COMPLETE WORLD. (Babylonian Talmud, Tractate Sanhedrin, 37a)

The fruits of our effort:

The battle against spiritual terrorism is being won, one soul at a time!!!
