Halakhah su Levitico 19:36

However, regarding the matter of lashes, there is a difference between [the examples]. As all those [simply] specified in one negative commandment only receive one [set of] lashes - for example, "the wage of a harlot and the price of a dog"(Deuteronomy 23:19); and "leaven and [...] honey" (Leviticus 2:11); "the case of a stranger [or] an orphan" (Deuteronomy 24:17), and all that is similar to them. But the negative commandments that [also] have a general category and are specified at the beginning or end [of the category] - for example, this negative commandment that specified "uncooked and boiled" and is [then] generalized, "Do not eat [...] but only roasted with fire"; and so [too], with a nazerite (Numbers 6:4), "from anything that is obtained from the grapevine [...] may he not eat," and afterwards it specifies, "seeds [...] or skin," ('and grapes wet and dry,' Numbers 6:3) - with these and those similar to them, we give lashes for each and every one. [This is] because the inclusion of the specification that was not needed, indicates lashes for each one [of them], as we have said. And the teacher was prolific in his proofs about this in the ninth shoresh in his Book of the Commandments - that the calculation of commandments is not the same as the calculation of [which commandments require] lashes [independently]. And that which I have said that Ramban, may his memory be blessed, will count each of the ones specified by their names individually - each one by itself - only when they are separate in their content, as we have written; [it] is, for example, [in the case of] 'leaven and honey,' [and] 'the wage and the price.' But in a case where it is the same content - even if they are specified by different names - they are only counted as one commandment. For example, "All male first-borns that are born in your herd and in your flock" (Deuteronomy 15:19) is only one commandment to sanctify all of the first-borns; and the specification is [also] only one commandment. And so [too], "All tithes of the herd or flock" (Leviticus 27:32) is only one commandment to separate to give the tithes of these animals. And so [too], "Judges and officers" (Deuteronomy 16:18) is only that we should establish justice through these people and it is one commandment. And so [too], "An honest balance, honest weights, an honest ephah, and an honest hin" (Leviticus 19:36) is all one commandment, that we should not lie about measures.

The commandment of having just scales, weights and measures: To have just scales, weights and measures and to be very careful about them, as it is stated (Leviticus 19:36), "You shall have just scales, just weights, a just eiphah, and a just hin." And the language of Sifra, Kedoshim, Chapter 8:7 [is] "'Just weights' - justify the scales precisely" - meaning to say, that the scales be righteous. And the matter is well-known regarding scales that there are important adjustments to make, as it is possible to do many types of falsehood with them. "'Just weights' - justify the weights precisely" - also with weights, it is also possible to do many types of falsehood, and similar to that which they, may their memory be blessed, said (Bava Metzia 61b), "I will repay in the future anyone who submersed his weights in salt." "'A just eiphah' - justify the eiphahs precisely; 'and a just hin' - justify the hin precisely." And an eiphah is a dry measure and a hin is a liquid measure. And the Torah warned us about each and every one of these things specifically, due to the severity of the matter - and even though it is all included in the principle of "And a man shall not cheat his compatriot." And the language of Sifra, Kedoshim, Chapter 8:10 [is] "On condition of this, I took you out from the Land of Egypt - that you accept upon yourselves the commandment of measures." And they, may their memory be blessed, also said (Bava Metzia 61b), "I am He Who distinguished in Egypt between the drop of a firstborn and the drop that is not of a firstborn, and I am [He Who is] destined to exact punishment from one who submerses his weights in salt" in order to cheat the creatures, since they do not notice it.
