Reference for Keritot 2:1
אַרְבָּעָה מְחֻסְּרֵי כִפּוּרִים וְאַרְבָּעָה מְבִיאִין עַל הַזָּדוֹן כִּשְׁגָגָה. אֵלּוּ הֵן מְחֻסְּרֵי כִפּוּרִים. הַזָּב, וְהַזָּבָה, וְהַיּוֹלֶדֶת, וְהַמְצֹרָע. רַבִּי אֱלִיעֶזֶר בֶּן יַעֲקֹב אוֹמֵר, גֵּר, מְחֻסַּר כַּפָּרָה עַד שֶׁיִּזָּרֵק עָלָיו הַדָּם. וְנָזִיר, לְיֵינוֹ וְתִגְלַחְתּוֹ וְטֻמְאָתוֹ:
[There are] four [persons] who are [considered] <i>Mechusar Kippurim</i> [one who has purified himself via immersion but who still needs to bring a sacrifice before eating sacrificial meat], and [there are] four [persons] who bring a sacrifice for intentional transgressions as [they would] for unintentional transgressions. The following are <i>Mechusar Kippurim</i>: A <i>Zav</i> [a man suffering from gonorrhea], a <i>Zavah</i> [a woman with a menstrual-type flow occurring at a time other than her normal period], a woman who has given birth, and a <i>Metzora</i> [one rendered severely impure from an unsightly skin disease; upon recovery and purification he must bring offerings]. Rabbi Eliezer ben Yaakov says: A convert [has the status of] a <i>Mechusar Kapparah</i> until the blood has been sprinkled [on the altar] for him; and <i>Nazir</i> [a person who swears abstention from all grape products like wine, from cutting his hair, and avoidance of corpse impurity] [depends on his sacrifices to be permitted] his wine, his hair-cutting and his impurity.
