Curiosity –
I’m not sure what’s in Shoftim perek 7 because I was in yeshiva
Well isn’t that a sad indictment of the yeshiva system (or at the very least, your yeshiva)…
So, just so you know, Shoftim 7 starts with Gidon having just been chosen to lead Bnei Yisrael against the Midianim. He recruits an army but H’ tells him that it is too large and will not showcase the miracle suitably, plus many of the soldiers are idol-worshippers. So Gidon performs a test. He takes the soldiers to the river-bank and tells them to drink; those that kneel down are discarded as idol-worshippers, those that “lapped like a dog” were kept. So, ironically, the action you say is “undignified for a ben Torah” is exactly how Gidon determined who was a Ben Torah.
