Halakhah for Ruth 2:14

In this explanation that I wrote here that the liability for minute swarming creatures is from the time that they go out on the ground and not before this, I am ignoring that which Rambam, may his memory be blessed, wrote about it - and even though I set out to hold on to his path. As he wrote in his book of commandments (Sefer HaMitzvot LaRambam, Mitzvot Lo Taase 179) that this negative commandment is from when they went out into the air or walked on the surface of the fruit. And we should wonder much about him with this, as we found explicitly in Chullin 67b, that this matter remains [unresolved] there - as it appears there, "Rav Yosef asks, 'If it separated to the air of the world, what is [the law]; on top of a date, what is [the law]?'" And even the rabbi himself wrote in his great essay (Mishneh Torah, Laws of Forbidden Foods 2:14, 16) that this matter is a doubt and [so] we do not administer lashes for it. And therefore, I put aside his explanation here, and I wrote [the commandment] by way of the truth. And here too did I find afterwards that Ramban, may his memory be blessed, (on the Sefer HaMitzvot LaRambam, Root 9) wondered greatly about him on this mistake.
