Rabbi Ḥanina would wrap himself in his garment and stand at nightfall on Shabbat eve, and say: Come and we will go out to greet Shabbat the queen. Rabbi Yannai put on his garment on Shabbat eve and said: Enter, O bride. Enter, O bride. The Gemara relates: Rabba bar Rav Huna happened to come to the house of Rabba bar Rav Naḥman. They brought before him three se’a of oiled biscuits. He said to them: Did you know I was coming and prepared all of this in my honor? They said to him: Are you more important to us than Shabbat? The biscuits were prepared in deference to Shabbat. Rabbi Abba bought thirteen plain staters [astirei peshitei] worth half a zuz of meat from thirteen butchers in deference to Shabbat, so that he would have various types of fine meat. And he would place the meats at the door hinge at the entrance to his house to hurry to bring another type of meat. And he said to the cooks, in order to rush them: Hurry and prepare it, hurry and prepare it. The Gemara also relates: Rabbi Abbahu would sit on an ivory chair [takhteka] and fan the fire cooking the food for Shabbat, in order to play a role in preparations for Shabbat. Rav Anan would don a simple black garment for the Shabbat preparations, as the school of Rabbi Yishmael taught: While wearing the garments in which he cooked a pot of food for his master, one should not dilute a cup of wine for his Master. One should wear a garment appropriate for the task at hand. Rav Safra would roast the head of an animal to prepare it for Shabbat. Rava salted a shibuta fish in deference to Shabbat. Rav Huna kindled lamps in deference to Shabbat. Rav Pappa spun the wicks for the Shabbat lamp. Rav Ḥisda cut the beets in preparation for Shabbat. Rabba and Rav Yosef cut wood. Rabbi Zeira prepared thin sticks for kindling. Rav Naḥman bar Yitzḥak would load objects on his shoulder and enter, load objects on his shoulder and exit. He said: If Rabbi Ami and Rabbi Asi happened to visit me, would I not load objects on my shoulder before them? So too, it is fitting to do so in deference to Shabbat. And some say that Rabbi Ami and Rabbi Asi would load objects on their shoulders and enter, load objects on their shoulders and exit. They said: If Rabbi Yoḥanan happened to come to visit us, would we not load objects on our shoulders before him?

[...] The halakhot of Shabbat, Festival peace-offerings, and misuse of consecrated property are like mountains suspended by a hair, as they have little written about them in the Torah, and yet the details of their halakhot are numerous. [...]
The laws of the Sabbath and the laws of the Festival Offering and the laws of Sacrilege, each have many laws which are dependent upon intimations, with scant Scriptural [support] are like mountains suspended by the hair of the head.
The acts of carrying out from a public domain into a private domain or vice versa, which are prohibited on Shabbat, are primarily two basic actions that comprise four cases from the perspective of a person inside a private domain, and two basic actions that comprise four cases from the perspective of a person outside, in a public domain. The mishna elaborates: How do these eight cases take place? In order to answer that question, the mishna cites cases involving a poor person and a homeowner. The poor person stands outside, in the public domain, and the homeowner stands inside, in the private domain. The poor person lifted an object in the public domain, extended his hand into the private domain, and placed the object into the hand of the homeowner. In that case, the poor person performed the prohibited labor of carrying from the public domain into the private domain in its entirety. Or, the poor person reached his hand into the private domain, took an item from the hand of the homeowner, and carried it out into the public domain. In that case, the poor person performed the prohibited labor of carrying out from the private domain into the public domain in its entirety. In both of these cases, because the poor person performed the prohibited labor in its entirety, he is liable and the homeowner is exempt. [...]
