레위기 14:7의 미슈나

He now comes to set free the living bird. He does not turn his face towards the sea or towards the city or towards the wilderness, for it is said, "But he shall let the living bird go out of the city into the open field" (Leviticus 14:53). He now comes to shave off the hair of the metzora. He passes a razor over the whole of his skin, and he [the metzora] washes his clothes and immerses himself. He is then clean so far as to not convey uncleanness by entrance, but he still conveys uncleanness as does a sheretz. He may enter within the walls [of Jerusalem], but must keep away from his house for seven days, and he is forbidden to have intercourse.
