신명기 23:11 해설: Rashi, Chizkuni, Ibn Ezra & Siftei Chakhamim

מקרה לילה [IF THERE BE AMONG YOU ANY MAN THAT IS NOT CLEAN BY REASON OF] UNCLEANNESS THAT CHANCETH HIM BY NIGHT — By night: Scripture speaks of what usually occurs (but the law applies also if the uncleanness happens at day time) (Sifrei Devarim 255:3).

מקרה לילה, “due to nocturnal emission of semen during the night;” the letter מ in the word מקרה here is a prefix not part of the word itself, just as it is in the word משדה in Leviticus 27,16: משדה אחוזתו, “part of his ancestral field.”

The mem in the word from an event is prepositional, like in “from his hereditary land” [Leviticus 27: 16].

ויצא אל מחוץ למחנה THEN HE SHALL GO ABROAD OUT OF THE CAMP — This is a command,

לא יבא אל תוך המחנה HE SHALL NOT COME WITHIN THE CAMP — This is a prohibition (Sifrei Devarim 255:4). He is forbidden to enter the “camp of the Levites”, and all the more so, the "camp of the Shechinah". (cf. Sifrei Devarim 255:5; Pesachim 68a and Rashi on Numbers 5:2).
