Tosefta do Psalmów 137:5

Just as those who belong to the courtyard can object to what happens in the joint courtyard, thus can the residents of an alleyway object to what happens in the joint alleyway. Howso? If one built a bathhouse next to his fellow’s bathhouse, a store within the store of his fellow, he cannot prevent him by saying, you have brought an obstacle to me, as the other can say, just as you do within your property so I do within my property. If one’s water was crossing onto the roof of his fellow and he went up and stopped it, he can prevent him from doing so, unless he knows in which place he will lead it. If the public way or a stream passed through one’s field and he got up and fenced it so that they cross through his fellow’s field, he can’t prevent him saying, you have brought an obstacle to me, as he can say, just as I do on my property, thus you can do on yours. Rabbi Yehudah says, The public that selected a path for itself, what it selects, it selects. If he has a cistern in his fellow’s courtyard, and the owner of the courtyard wants to dig another cistern, he can prevent him. But he cannot make it a public well or a public immersion pool, and he cannot fill it and give water [to his animals] or fill it and sell it. But he may fill it and water [animals] in the marketplace and sell in the marketplace. If he bought a courtyard and within it were brackets and balconies, and they fell, he can build them in their place. He may not paint, or plaster, or stucco. If he bought a house that was pained or plastered or stuccoed, he has the power over that. A man can plaster his whole house but he leaves a part out as a memory of Jerusalem. A person makes all the parts of a meal but leaves out part as a memory of Jerusalem. A woman does all her makeup but leaves part as a memory of Jerusalem, as it says, “If I forget you, o Jerusalem, let my right wither, let my tongue stick to my palate” (Psalms 137:5-6). All who mourn for her in this world will be happy with her in the next, as it says, “Rejoice with Jerusalem and be glad for her, all you who love her. Join in her jubilation, all you who mourned over her” (Isaiah 66:10).

Rabbi Ishmael said: From the day that the Temple was destroyed, it would be appropriate that we not eat meat or drink wine (since these were used in the Temple service). But a court does not decree (restrictions) on the community which they cannot uphold. He would say that since they (the Romans) decree upon us that we not learn Torah, we should decree upon the community that they not marry women (since they do not know marriage and family laws), and not have children - and as a consequence, the seed of Abraham will cease. Rather, leave Israel alone (to continue to do as they now do, marrying and having families); it is better that (if they transgress), they do so inadvertently and not intentionally. § From the time that the last Temple was destroyed, the number of ascetics (perushin) proliferated in Israel, who would not eat meat or drink wine. Rabbi Yehoshua joined them. He said to them, "For what reason are you not eating meat?" They said to him, "Shall meat be eaten, when every day the daily offering was offered up on top of the Altar, and now it has ceased?"^*cf. Chag. 7a:9 ("Your table should not be full [of meat] while your Master's table (i.e., the Altar) is empty.") He said to them, "Let it not be eaten. And for what reason are you not drinking wine?" They said to him, "Shall wine be drunk, when every day they would pour the libation offering on top of the Altar, and now it has ceased?" He said to them, "Let it not be drunk." He said to them, "And if so, neither should bread be eaten, for from that they would bring the two loaves and the showbread. Nor should water be drunk, for from that they would perform the water libation on Sukkot. Nor should figs and grapes be eaten, for from them they would bring the First Fruits on Shavuot." They were silent. He said to them, "My children, it is impossible to mourn excessively, and it is impossible not to mourn at all. Rather, thus said the Sages: A man may plaster his house with lime, but leave over a small amount [unplastered] as a remembrance of Jerusalem. A man may make all the preparations for a feast, and leave over a small amount as a remembrance of Jerusalem. A woman may fashion any kind of jewelry, and leave over a small amount as a remembrance of Jerusalem. As it is said (Ps. 137:5-6), 'If I shall forget thee, Jerusalem, let me forget my right hand, and let my tongue cleave to the roof of my mouth if I cease to remember you.' And all those who mourn her in this world [even in moderation] will celebrate with her in the world to come, as it is said (Is. 66:10), 'Rejoice with Jerusalem and exult in her, all those who love her. [Be joyous in her jubilation, all those who mourn her.].'"
