הלכה על כריתות 8:29

And do not think to say that this negative commandment of "You may not" is a general prohibition, as each and every matter is a negative commandment on its own. And so is it explained in Tractate Makkot (it should say Keritot 4b), "If he ate tithe of grain, wine and oil, he is liable for each and every one." And it challenges there, "And do we administer lashes for a general prohibition?" And it answers it, "The verse is superfluous. How is it? It is written (Deuteronomy 12:23), 'And you shall eat in front of the Lord, your God [...] the tithe of your grain, your wine and your oil.'" [This discussion continues in Makkot 18a:] "Let the [Torah] write, 'You may not eat them in your gates.' Why do I need the [Torah] to enumerate all of them here? [Hence] we understand from it [that it is] to designate for them a negative commandment for each and every one." And this verse of "And you shall eat" is at the end of this Order.
