The Greek that is translated as “wineskins” in most English translations is translated in Guhu-Samane as “gourds.”
“Wineskins” caused “puzzlement [because] why would one put wine or any liquid into the skin of an animal since the skins just rot quickly? [But] it is conceded that a person wishing to store a liquid (wine or other) would not choose an old, but a new gourd. The people here are familiar with wine in the Eucharist and can readily conceive of how wine (literally ‘strong water’) could burst an old gourd and as such the argument is not lost.”
