He used to say:Beloved is man for he was created in the image [of God]. Especially beloved is he for it was made known to him that he had been created in the image [of God], as it is said: “for in the image of God He made man” (Genesis 9:6). Beloved are Israel in that they were called children to the All-Present. Especially beloved are they for it was made known to them that they are called children of the All-Present, as it is said: “your are children to the Lord your God” (Deuteronomy 14:1). Beloved are Israel in that a precious vessel was given to them. Especially beloved are they for it was made known to them that the desirable instrument, with which the world had been created, was given to them, as it is said: “for I give you good instruction; forsake not my teaching” (Proverbs 4:2).

How did they admonish witnesses in capital cases? They brought them in and admonished them, [saying], “Perhaps you will say something that is only a supposition or hearsay or secondhand, or even from a trustworthy man. Or perhaps you do not know that we shall check you with examination and inquiry? Know, moreover, that capital cases are not like non-capital cases: in non-capital cases a man may pay money and so make atonement, but in capital cases the witness is answerable for the blood of him [that is wrongfully condemned] and the blood of his descendants [that should have been born to him] to the end of the world.” For so have we found it with Cain that murdered his brother, for it says, “The bloods of your brother cry out” (Gen. 4:10). It doesn’t say, “The blood of your brother”, but rather “The bloods of your brother” meaning his blood and the blood of his descendants. Another saying is, “The bloods of your brother” that his blood was cast over trees and stones. Therefore but a single person was created in the world, to teach that if any man has caused a single life to perish from Israel, he is deemed by Scripture as if he had caused a whole world to perish; and anyone who saves a single soul from Israel, he is deemed by Scripture as if he had saved a whole world. Again [but a single person was created] for the sake of peace among humankind, that one should not say to another, “My father was greater than your father”. Again, [but a single person was created] against the heretics so they should not say, “There are many ruling powers in heaven”. Again [but a single person was created] to proclaim the greatness of the Holy Blessed One; for humans stamp many coins with one seal and they are all like one another; but the King of kings, the Holy Blessed One, has stamped every human with the seal of the first man, yet not one of them are like another. Therefore everyone must say, “For my sake was the world created.” And if perhaps you [witnesses] would say, “Why should we be involved with this trouble”, was it not said, “He, being a witness, whether he has seen or known, [if he does not speak it, then he shall bear his iniquity] (Lev. 5:1). And if perhaps you [witnesses] would say, “Why should we be guilty of the blood of this man?, was it not said, “When the wicked perish there is rejoicing” (Proverbs 11:10).]
מתני׳ כופין אותו לבנות בית שער ודלת לחצר רבן שמעון בן גמליאל אומר לא כל החצרות ראויות לבית שער כופין אותו לבנות לעיר חומה ודלתים ובריח רשב"ג אומר לא כל העיירות ראויות לחומה
MISHNA: The residents of a courtyard can compel each inhabitant of that courtyard to financially participate in the building of a gatehouse and a door to the jointly owned courtyard. Rabban Shimon ben Gamliel disagrees and says: Not all courtyards require a gatehouse, and each courtyard must be considered on its own in accordance with its specific needs. Similarly, the residents of a city can compel each inhabitant of that city to contribute to the building of a wall, double doors, and a crossbar for the city. Rabban Shimon ben Gamliel disagrees and says: Not all towns require a wall.
כמה יהא בעיר ויהא כאנשי העיר י"ב חדש קנה בה בית דירה הרי הוא כאנשי העיר מיד:
With regard to this latter obligation, the mishna asks: How long must one live in the city to be considered like one of the people of the city and therefore obligated to contribute to these expenses? Twelve months. But if he bought himself a residence in the city, he is immediately considered like one of the people of the city.
ולכל מילי מי בעינן י"ב חדש והתניא שלשים יום לתמחוי שלשה חדשים לקופה ששה לכסות תשעה לקבורה שנים עשר לפסי העיר אמר ר' אסי אמר ר' יוחנן כי תנן נמי מתניתין שנים עשר חדש לפסי העיר תנן:
The Gemara asks: And do we require that one live in a city for twelve months for all matters? But isn’t it taught in a baraita: If one lives in city for thirty days, he must contribute to the charity platter from which food is distributed to the poor. If he lives there for three months, he must contribute to the charity box. If he lives there for six months, he must contribute to the clothing fund. If he lives there for nine months, he must contribute to the burial fund. If he lives there for twelve months, he must contribute to the columns of the city [lepassei ha’ir], i.e., for the construction of a security fence. Rabbi Asi said that Rabbi Yoḥanan said: When we learned twelve months in the mishna, we learned that with regard to contributing to the columns of the city, money used for protecting and strengthening the city, but not for other matters.
