Pesachim 134
כי האי גוונא זב נמי טמויי מטמי באונס כדרב הונא דאמר רב הונא ראיה ראשונה של זב מטמאה באונס
<br> To that extent a zab too is certainly defiled through an accident, in accordance with R. Huna. For R. Huna said: The first discharge of a zab defiles [when it is caused] by an accident. <br>
מאי חומריה דמצורע מזב שכן טעון פריעה ופרימה ואסור בתשמיש המטה אדרבה זב חמור שכן מטמא משכב ומושב ומטמא כלי חרס בהיסט
What is the greater stringency of a leper over a zab? Because he requires peri'ah and rending [of garments], and he is forbidden sexual intercourse. On the contrary, a zab is more stringent, because he defiles couch and seat, and he defiles earthen vessels by hesset? - Scripture saith, [instead of] 'a leper', 'and every [kol] leper' to include a ba'al keri; and a leper is more stringent than a ba'al keri, and what is his greater stringency? As we have stated. On the contrary, a ba'al keri is more stringent, because he defiles by the smallest quantity [of semen]? - He agrees with R. Nathan. For it was taught, R. Nathan said on the authority of R. Ishmael: A zab requires [a discharge of matter] sufficient for the closing of the orifice of the membrum, but the Sages did not concede this to him. And he holds that a ba'al keri is assimilated to a zab. What is the purpose of 'and every [kol] leper'? - Since 'every one [kol] that hath an issue' is written, 'every [kol] leper' too is written. <br>
ומאי חומריה כדאמרן אדרבה בעל קרי חמור שכן מטמא במשהו
days, but only until evening, while a reptile too defiles until evening only, think, if zabin and lepers forced their way through and entered the Temple Court at a Passover sacrifice which came in uncleanness, - you might think that they are culpable; therefore it is stated, ['Command the children of Israel,] that they send out of the camp every leper', and every one that hath an issue [zab], and whosoever is unclean by the dead': when those who are unclean by the dead are sent out, zabin and lepers are sent out; when those who are unclean by the dead are not sent out, zabin and lepers are not sent out.
סבר לה כר' נתן דתניא ר' נתן אומר משום ר' ישמעאל זב צריך כחתימת פי האמה ולא הודו לו חכמים ואיתקש ליה בעל קרי לזב
The Master said: '"And every [kol] one that hath an issue" is to include a ba'al keri'. This supports R. Johanan. For R. Johanan said: The cellars [under the Temple] were not consecrated; and a ba'al keri is sent without the two camps. <br>
וכל צרוע למה לי איידי דכתיב כל זב כתיב נמי כל צרוע
An objection is raised: A ba'al keri is like [a person defiled through] contact with a reptile. Surely that means in respect of their camp? No: [it means] in respect of their uncleanness. [You say] 'In respect of their uncleanness!' [Surely] uncleanness until evening is written in connection with the one, and uncleanness until evening is written in connection with the other? Hence it must surely mean in respect of their camp! - No: after all [it means] in respect of their uncleanness, and he informs us this: that a ba'al keri is like [a person defiled through] the contact of the reptile: just as the contact of a reptile defiles [even] accidentally, so is a ba'al keri defiled [when the semen is discharged] accidentally. An objection is raised:<br>
ההוא מיבעי ליה לכדתניא רבי אליעזר אומר יכול דחקו זבין ומצורעין ונכנסו לעזרה בפסח הבא בטומאה יכול יהו חייבין ת"ל (במדבר ה, ב) וישלחו מן המחנה כל צרוע וכל זב וכל טמא לנפש בשעה שטמאי מתים משתלחין זבין ומצורעין משתלחין אין טמאי מתים משתלחין אין זבין ומצורעין משתלחין
