Yerushalmi Chagigah 3:6 ירושלמי חגיגה ג׳:ו׳

MISHNAH: Tax collectors¹⁷⁹Vulgar Jews entering the house of a fellow. who entered a house, and also tax collectors who returned implements¹⁸⁰, are trustworthy if they say “we did not touch”. And in Jerusalem they¹⁸¹Every Jew. are trustworthy about sancta, and on holidays also about heave.

HALAKHAH: “If tax collectors entered a house, the house is impure. If they are accompanied by a Gentile they are trustworthy to say, we entered but we did not touch.¹⁸²Mishnah Taharot 7:6. Tosephta Taharot 8:5 explains that even though the Gentile is no formal witness, the tax collectors fear to lie in the presence of people who know better.” One may explain this by two explanations. They are trustworthy to say, we entered but we did not touch if witnesses know of it¹⁸³Probably this should be read as “no witnesses know of it.” In this case it would be an application of the principle, “the mouth which forbade is the mouth which permits.” If no witness knows that he entered, the house would be impure only by his testimony. But if one believes him in this one also must believe him that he did not touch and therefore the house is pure.. And in Jerusalem they are trustworthy about sancta even if witnesses know of it. One may explain by another explanation: They are trustworthy to say, we entered but we did not touch. This is necessary {to be stated} even if witnesses know of it. And in Jerusalem they are trustworthy about sancta even if witnesses know of it.

Rebbi Joshua ben Levi said, Jerusalem, built like a city which combines in fellowship¹⁸⁴Ps. 122:3. The Babli 26a quotes another verse., the city which confers fellowship on all of Israel¹⁸⁵All of Israel are presumed to strictly observe all rules of purity.. Then even on all other days of the year? Rebbi Ze`ira said, in the time when the tribes ascended¹⁸⁶Ps. 122:4, the holidays of pilgrimage..
