3. [If] one discharged thick drops from the member, he is tamei; [these are] the words of R’ Elazar Chisma. [If] one had [bad] thoughts at night and arose and found his flesh warm, he is tamei.                A woman who emits semen on the third day is tahor; [these are] the words of R’ Elazar ben Azaryah. R’ Yishmael says: Sometimes it is four periods, sometimes five, [and] sometimes six. R’ Akiva says: It is always five [periods].

4. [If] a Gentile woman emitted the semen of a Jew, it is tamei. [If] a Jewish daughter emitted the semen of a Gentile, it is tahor. [If] a woman had intercourse and she went down and immersed herself, but had not cleaned out her house, it is as if she did not immerse herself.                A baal keri who immersed himself and did not pass water becomes tamei when he does pass water. R’ Yose says: In [the case of] a sick man or an old man, he becomes tamei; [but] in [the case of] a young and healthy person, he is tahor.

5. [If] a niddah put money into her mouth, and she went down and immersed herself, she is purified of her tumah, but she is [still] tamei on account of her saliva. [If] she put her hair in her mouth, [or] she clenched her hand, [or] she pressed her lips together, it is as if she did not immerse herself. [If] one holds a person or utensils and immerses them, [they] remain tamei; but if he rinsed his hands in water, they become tahor. R’ Shimon says: He may loosen [his hold] so that the water should enter in between. Concealed areas [and] folded areas do not require that the water should enter into them.

1. The following [items] intervene in the case of a person: woolen threads, linen threads, and the ribbons on girls’ heads. R’ Yehudah says: [Those] of wool and of hair do not intervene, because the water passes between them.
