The "Oat Brit" [Os Bris] Pattern
First - please see these sections
P B'reishis R'vii 4:15
P. Noach Hamishi 9:5-17
P. Lech Lecha Shishi-Sh'vii 17:2-21
P. Ki Tissa End of Rishon 31:13-17
In the last 3 Oat and Brit [Os and Bris] appear in tandem, often repeatedly. Re: Kayin, only "Oat"
Have any "Parshanim" connected all of these dots together?
EG the number of times Oat and Brit are used? The sequencing?
For a limited example -
See Torah Temimah on Lech Lecha 17:11 quoting a Meimra from Rav Nachman bar Yitzchok in TB: Shabbat 132a, concerning "Meelah docheh Shabbos" which addresses a small subset of this pattern.
