Halakhah zu Könige I 6:39

Rav Hisda said, “if someone has eaten meat, he is forbidden to eat cheese, but if he ate cheese first, he is permitted to eat meat,¹⁶⁸Ibid., 105a. and Rav Hisda’s view is the accepted view.¹⁶⁹So the Tur and Shulhan Arukh Yoreh Deah 89. But surely he said, “He is forbidden to eat cheese until another meal.” Indeed, for a whole day is a more stringent practice, and thus it was when Mar Ukba’s practice was to wait only until the next meal. For Mar Ukba said, “I am in this matter like ‘Hametz the son of Wine,’ for if my father would eat meat he was fastidious and wouldn’t eat cheese till the same time the next day. But while I won’t eat it at the same meal, I’ll eat it at the next meal.¹⁷⁰B. Hullin 105a. And the custom of Mar Ukba’s father to wait for a whole day is extra stringent, so accordingly we follow Mar Ukba’s practice, even though he said, “I am in this matter like Hametz the son of Wine.” And so it is our practice to wait just until the next meal. Hence, it is not sufficient just to wipe one’s mouth or to wash one’s hands, since meat is not digested after the first meal for at least six hours, and meat caught in between the teeth is still meat, as it is said, “The meat was still between their teeth.”¹⁷¹Nu 11:33, a reference to the quail meat God over-fed the Israelites in response to their complaining in the desert. But if one eats cheese, he is permitted to eat meat without any delay at all. He only has to wipe his mouth whether it’s day or night, and wash his hands if it’s at night, but not if it’s during the day, nor does it make a difference whether it’s game or meat from a domesticated animal.¹⁷²An so also the Tur and Shulhan Arukh Y.D. 89:1. Poultry and cheese are eaten “like an epicurean,”¹⁷³B. Hullin 104b, which Rashi explains to mean “without any qualms,” as libertines eat. which I found in the explanation of the Arukh to mean without wiping one’s mouth or washing their hands whether in the day or in the night.¹⁷⁴Sefer Ha-Arukh, the Dictionary of R. Natan ben Yehiel of Rome (11th century). The reason given was that mayim ahronim are an obligation, because a person eats salt after his meal, which contains Sodomite salt that blinds the eyes, even one grain in a kor of regular salt,¹⁷⁵Sodomite salt – salt from the Dead Sea. Potent stuff. Even in a mixture of one grain to a kor (about 530 liters) of regular salt would blind you ! It was customary to eat a little salt for “dessert,” presumably to “kill” anything potentially harmful in the food one has just eaten. See Rabbi Levi Cooper, “World of Our Sages: Salty Hands,” <http: www.pardes.org.il="" weekly-talmud="" 2009-02-12.php="">. though no blessing is required, except for someone who is saying a blessing over washing dirty hands. For just as a polluted priest was unfit for the Temple service, someone whose hands are polluted is unfit to say a blessing. What does it mean to be “polluted”? Anything that is not fit to be brought near the altar, such as an animal or birds, but whatever is fit does not require washing, since it isn’t something that’s polluted. However, there are some among the great teachers who are of the opinion that anything can be polluted.

One also has to careful when about to say birkat ha-mazon to remove the knife from the table. The reason for this practice is because the table is called an “altar,” and just as on an altar we have been warned not to brandish something made of iron over it, as it is said, “do not build it [an altar] of hewn stones, etc.”¹⁹⁴Ex 20:22. The rule of Torah is that if one makes it into an altar of hewn stones with a tool of silver or flint, it is permitted. For the point of the prohibition is not against it being hewn, but rather because it is hewn with something made of iron, i.e., a sword, and Torah kept it far from the tabernacle, when it is written: “gold, silver, and copper,”¹⁹⁵Ex 25:3. but does not mention iron there. And likewise with the sanctuary it is written, “No hammers or axe or any iron tool was heard in the House when it was being built.”¹⁹⁶I Kings 6:7. The reason is because that is the power of Esau with what he was blessed from his father’s mouth; this is what is meant by “By the sword you shall live,”¹⁹⁷Gen 27:40. and it is written, “but Esau I hated.”¹⁹⁸Mal 1:3. Therefore it is kept far from the sanctuary. And likewise at the table we have been warned to remove the sword from it, because the sword is something destructive¹⁹⁹The pun ha-herev hu ha-mahriv is lost in the translation. and the source of destruction, the opposite of peace, and it does not belong in a place of blessing, i.e., peace. For indeed the altar and the table prolongs a person’s days, while a sword shortens them, and it makes no sense to brandish something that shortens over something that prolongs life.²⁰⁰Mekhilta Yitro (end).
