תלמוד על חגיגה 3:6

It was stated: “One does not raise chickens in Jerusalem because of the sacrifices, nor may Cohanim in the Land of Israel because of purities.” I could think also in Jerusalem in this way⁹⁸That people eating sacrifices may not raise chickens but all others may., but it might follow what Rebbi Joshua ben Levi said, “Jerusalem the built-up⁹⁹Ps. 122:3. The argument is about the second half of the verse which is not quoted: “A city joined together.” All its inhabitants are joined in its holiness.
In Ḥagigah 3:6, The same remark by R. Joshua ben Levi’s is given quite a different interpretation.” etc., the city which joins Israel one to the other.
