I have yet to find one of your ideas that conforms to what the synoptics, the recap in I cor 10, 2 Cor 3 and Heb 9-10 on heb 8 actually says. Your club fixates on one line in Heb 8 for extraneous reasons. Extraneous means the reasons Heb 8 quotes Jer are not the reasons you fixate on that one line about Israel and Judah.
In terms of a line count, that's about 1% of NT material. That is how accurate you are. The alpha-digits 'new covenant' are there, and that is the only connection to the reality of the text.
