I'm following a reference to "Chazon Ish,Yev., par. 83, #6", which I think is his commentary on Yevamot. Can anyone help me find this source online? Many thanks.
Thanks to Shmuel (I had no idea the Chazon Ish was on Hebrewbooks), here are some possibilities.
If par. 83 means simman 83, here is a link, although that's hilchos gitin and not relevant to the reference at hand.
His commentary on Yevamos starts at simman 134, so I'm not sure what's par. 83 in this case.
If it means daf 83, I don't see comments there.
There's also Hilchos Yibum starting at Simman 115.
I'm thinking they meant Simman 117 par. 6, which says what they reference about someone acting like a Jew needing conversion or not. Maybe the Simman number changed over the years?
