DY: Thanks. I’m not doubting the CC, but I still couldn’t find it in the Shittah, and it is not pashut to say that Yissachar-Zevulan is Tzedakah and not a partnership.
Either way, it still is behind Bais HaKenesses and Yeshiva Tuition, which was my point.
Which one is more Kadosh != which is more important or “higher” (which I don’t know what you mean by that).
