Mod-80. So, where is todays specially appointed “kohen gadol” and his tzibbur? Why do they not get together daily and say tehillim every day after davening for “acheinu kul beis yisroel” like I do (and many people I know) instead of waiting until shabbos to recite a specific mi shebeirach. This also means, that you are equating border patrol duty with going to war (which I am not necessarily disagreeing with – I just have not thought it out all the way).
What is the source for your statement? I assume it is a mishna or gemara somewhere. How large a portion of klal yisroel are we talking about? 20%? more? Less? a designated number of people, say 25,000? How were those people chosen? Volunteer?
