These are two seperate sections, separated by a setuma break, but we darshen semuchin in Devarim, and elsewhere. And so Baal HaTurim writes what he writes.
To the right is the uncensored version and another copy of the same printing, but apparently censored.
The first change is that the original has shelo yitarvu im haumot, vehaumot nimshelo livhemot. By hand, someone clarifies in both cases akum, meaning ovdei kochavim umazalot. This perhaps relaxes the condemnation, restricting it to heathens, perhaps in accord with Meiri. I don't know that Baal HaTurim would have intended it as such, though. I saw in another Tanach that it put Kutim in both places instead, perhaps with similar results. And perhaps most interesting is in our own Mikraos Gedolos, which has shelo yitarvu im haakum, otam shenimshelu livheimot. This is but a minor change, but with drastically different implications, since it is selecting only those who are nimshelu on the basis of their behavior.
More puzzling is the second thing changed in the image above. The words crossed out are sheassur legaddel chazirim. So much so that I was thinking this might just be spilled ink; but elsewhere in the sefer are crossed out phrases, so this is likely one as well.
As far as I understand this Baal Haturim, he is darshening another semichut. The pesukim state:
And Baal Haturim is noting the end words of pasuk 7 and the beginning words of pasuk 8, and making a derasha on lachem as ownership, such that even owning and thus raising a pig is forbidden.
But what would the censor find offensive in this? Is it because the gemara juxtaposes and almost equates learning Greek wisdom with raising swine? This would be unlikely. My best guess at the moment is that this was simple ignorance on the part of the censor. I would not guess that he wanted to censorthe earlier part, he saw vesamich leih and censored the text after the second one. But it is possible that he mistakenly associated vesamich leih in the later text and thought that Baal HaTurim was equating the chazirim with the aforemention umot, where Baal Haturim was really making his derasha on the word lachem of the pasuk which is actually juxtaposed.
Unless I am the ignorant one here, and there is some obvious or fine point I am missing. Does anyone spot anything plausibly offensive in this?
