Musar do Liczb 15:22

וכי תשגו ולא תעשו את כל המצות האלה . Midrash Tanchuma as well as the Yalkut Shimoni, have the following comment on Leviticus 4,2: "When a person unknowingly commits a transgression in respect of any of G–d's negative commandments, etc." They say that this verse teaches us that transgression of any prohibition is equivalent to transgression of all of the Torah's commandments. Conversely, the Reishit Chochmah writes in Parshat Nasso, that if one performs a single positive commandment in all its pertinent details, it is as if one had performed all 248 positive commandments. The reason of course, is that there is no מצוה that does not contain some element of all the other מצות. Having said this, we understand why transgression of a single negative commandment is viewed as if one had transgressed all of them, seeing that it involved negation of those particular elements of all the other negative commandments that were associated with the single negative commandment one has flouted. This is the real meaning of the wording of the verse quoted above in 15,22.
