Can a person be held responsible for two simultaneous violations?
Should one prune a tree on Shabbat in order to make use of its branches, states Rabbi Cahana, he is guilty of two violations. By detaching any growth from its source he has performed one of the 39 categories of creative labor prohibited on Shabbat. In addition, his removing surplus branches will make the tree grow better so he is also guilty of promoting agricultural growth akin to planting.
In regard to Shabbat itself, when the punishment for willful violation is capital punishment, the only application of this "double trouble" is the need to bring two sins offerings as sacrifices if he did this pruning as an involuntary desecration of Shabbat. But if he did this voluntarily on Yom Tov or in the Shmitah year, he will be liable for two sets of lashes.
This seems to run counter to the rule which is often found in the Talmud that one cannot be held responsible for two violations committed simultaneously and only the severer punishment is applied.
Tosefot solves the problem by pointing out that this rule applies only when the punishments are of a different scale, such as a penalty of death and a penalty of lashes. In a case where the penalties are of the same level such as lashes for doing the above-mentioned pruning on a holiday or during the Shmitah year, this rule does not apply because we view the two penalties of lashes as a single unit.
An example of this cited by Tosefot is the ruling by the Sage Abaye (Pesachim 24a) that one can be guilty of four violations — and punished by four sets of lashes — for consuming a particular insect which is forbidden by the Torah under four different categories.
What the Sages Say
"One should not marry on Chol Hamoed because one should focus on the joy of the holiday alone and not mix it with another sort of joy."
- Rabbi Elazar quoting Rabbi Chanina - in explanation of the Mishneh (Mo’ed Katan 8b)
