[In this Chapter, we] shall Explain [Concerning] the Punishment of the Habitual Speakers of Lashon HaRa
Notice the extent of the severity to which the Torah deals with the impurity of the metzora. [The Torah treats the metzora’s impurity as] more severe than the impurity of the zav, the ba’al keri, and one impure from coming into contact with the dead. [In contrast to the zav and ba’al keri, the metzora] is not allowed to remain anywhere within the Israelite camp, as it says “He shall sit alone outside the camp of his habitation”. (Vayikra: 13; 46)
[Our Sages of Blessed Memory] have said [in maseches “Arachin” (16b)]: “What is unique about the metzora, concerning whom the Torah said “he shall sit alone…”? He caused [there to be separation between man and wife [and] between man and his fellow. Therefore the Torah decreed: He shall dwell in isolation. Rabbi Yehoshua ben Levy said: What is unique about the metzora, [concerning whom] the Torah said he will bring two birds to purify himself? The Holy One, Blessed is He, said: [The metzora] performed an action of a babbler; he should bring a sacrifice of babblers.”
 A “confined metzora” is a person who has the Kohen confirmed to have tzara'as.
 “I”, in this verse, refers to HaShem.
 “Gemara” is Aramaic for “Talmud”.
 “Metzora” is one with a spiritual affliction, somewhat similar to leprosy – מצורע (Metzora) can also be read as a shortened version of the words "מוציא רע" as in "מוציא שם רע" (Motzi Shem Ra) – one who brings out an evil name by speaking slanderously against a person. "מוציא שם רע" usually refers to one who speaks slander about a person which is false.
 A male with gonorrhea who has one discharge becomes impure for the following twenty-four hours. If on the same or the following day he has a second discharge, he remains impure for a week. If there are three discharges, he must also bring a sacrifice after his week of impurity.
 One who has an emission of semen is impure and then immerses in a mikvah. Following the first nightfall after his immersion, he is pure.
 “Babbler” can also refer to birds who incessantly chirp. In this context, we see that the metzora was afflicted with tzara'as due to his speaking that which is forbidden, likely due to his involvement in speaking excessively.
