curiosity im not arguing on the meforshim. Based on what you are saying though the meforshim are arguing on the pesukim.
But ok, lets ignore the pesukim which specificly mention lying down to drink (R”chl). Please explain to me practicly how you (mis)understood the incident:
The people approach a body of water, their hands are about 3 feet or so away from the water, their face 5 feet or so, how exactly did those accepted get the water up to their face , what is the correct next step? (Hint it is not “I’m sorry gidon I cant drink because “it’s not lechatchila for a ben Torah to bend over and drink from a fountain”)
(Just to be clear according to the pesukim, which obviously the meforshim dont argue on) they lay down and “lapped like dogs this is beferesh in the pasuk and I have not seen anyone argue besides you)
