Our Gemara on Amud Aleph discusses a halachically sophisticated approach toward materials. There is an idea, which comes up various times in Halacha regarding something that is bound toward separation, and there’s nothing holding it back. In such a scenario, it may already be seen in certain circumstances as separated. 

In our Gemara’s case, there is a discussion of immersing a utensil with a long handle that is meant to be cut off. There is an argument that since this part is going to be cut off, it is already seen as removed and not a barrier. The particulars are debated by rishonim and have many implications in practical Halacha such as if hair or fingernails that are to be removed present a barrier right now to immersion or not. Regardless, the Gemara asserts that with certain materials, there is a unanimous opinion that they are considered separated immediately. For example, food which is meant to be cut up and divided is already considered separate, even when in contact with its parts.

There is also a practical halachic manifestation of this regarding the requirement that on Shabbos a blessing is to be recited on two whole loaves. What if one loaf has a portion that is completely charred? Right now, it is still attached and so technically the loaf is whole. However, since that part is to be detached, since it is nonconsumable and charred, perhaps the loaf is not considered whole. This is debated halachically, see Mishna Berurah (274:2) and Shaarei Teshuva (ibid 274:1). In general, many seemingly irrelevant and technical aspects of halachic discussion in the Gemara which seem to be anachronistic often end up being used as precedent for much more practical and everyday situations.

While on this topic, let us take a closer look at this requirement for a double loaf (Lechem Mishne). The source is a Gemara (Shabbos 117a):

“On shabbos a person is obligated to break bread in his meal over two loaves of bread, as it is written: ‘And it happened on the sixth day, they collected double the bread, two omer for each one’ (Exodus 16:22).”

It would seem that the requirement of two loaves is to memorialize and relive the experience of the double portion of Manna in the wilderness. Going deeper, the experience of the double portion in the wilderness has its own implications of the state of mind and experience of Shabbos. The preparations must be done the day before, and then experience the benefit on Shabbos. This is symbolic of having completed all work prior to Shabbos, and now after adequately preparing, being able to enter into the meditative and tranquil state of Shabbos.

Yet, there is a question here. The Manna was collected on Friday. If so, there ought to be an obligation specifically on Friday to prepare the two loaves. We don’t find that mentioned anywhere. The simple answer is that on a practical level, the hustle and bustle of everyday life does not allow for that focus. So, while technically the double loaves commemorate the fact that they came on Friday, we do not enact it specifically on Friday, but rather reflect on it over Shabbos by making the blessing over the double loaves.

It is interesting that the section of the Gemara that is immediately prior to the description of the double loaves talks about the importance of preparing for Shabbos on Friday. It states, “A person should always rise early on Friday in order to prepare all of the expenditures for shabbos, as it is written with regard to the collection of the Manna: ‘And it shall be on the sixth day, and they will prepare that which they have brought’ (Exodus 16:5), indicating that the children of Israel would begin preparing the food for shabbos immediately upon collecting the manna in the morning.”

If not an actual requirement to prepare the double loaves on Friday, it does show a connection between the two ideas of preparing for Shabbos in advance and the double loaves on Shabbos.

Midrash Tehilim (92) notices that there are a number of doubles that occur on Shabbos. There are the double loaves, but there are also the two lambs brought as a sacrifice, the dual words Zachor and Shamor used in the first and second description of the Ten Commandments, implying equal importance of preserving the Shabbos and actively commemorating it (Shavuos 20b), and a few other doubles cited in that Midrash. The Maharal (Gur Aryeh, Devarim 5:12) notes that this duality represents something about the essence of Shabbos. It is an integration of the material and the physical, an experience of the world to come being brought down into the present world. When we present these double loaves at our table, we are also experiencing the integration of the divine non-material non-physical world being brought into our physical world. The essence of Shabbos represented by the cessation of human labor and activity is in order to cultivate and channel a supernatural state that is about the world to come. It is a world where we do not have to engage in the physical and is purely experienced by the intellect and soul. However, in this world, it always is a duality. There always has to be the labor and preparation prior in order to achieve that state. While the seventh day may be the most important and maybe the pinnacle, we must have the six days first.
