The Mishnah: Some quotes

SIXTH DIVISION: TOHOROTH ('CLEANNESSES')
NIDDAH ('The Menstruant'), 5. 3--5. 5
p. 750: [See p. 749 and p. 751 for context.]

5. 3. A girl one day old^I can become unclean by virtue of being a menstruant. A girl ten days old² can become unclean by reason of a flux. A boy one day old can become unclean by reason of a flux, and he can become unclean from leprosy-signs, and he can become unclean from corpse-unclean-ness; he suffices to hold [his childless brother's widow] in the bonds of levirate marriage,³ and to exempt [his mother] from levirate marriage;⁴ he suffices to render [his mother] qualified to eat Heave-offering, or to render her unqualified to eat Heave-offering;⁵ and he can inherit property and bequeath it;⁶ he that kills him is culpable; and he counts as a full relative⁷ to his father and his mother and to all his kinsfolk.
5. 4. A girl three years old and one day may be betrothed by intercourse;⁸ her deceased childless husband's brother can acquire her⁹ by intercourse; and by connexion with her a man can be culpable by virtue of the law of a married woman;^I0 and him that has connexion with her [while she is a menstruant] she renders unclean so that he conveys uncleanness to what is beneath him in like degree as [he that has a flux conveys uncleanness] to what lies above him;^II if she is married to a priest she may eat of Heave-offering;^I2 if one that is ineligible^I3 has connexion with her he renders her ineligible for marriage with a priest; if any of the forbidden degrees^I4 prescribed in the Law had connexion with her they are put to death on her account, but she is not culpable. If she is younger than this, it is as one that puts a finger in the eye.
5. 5. If a boy nine years old and one day had connexion with his childless brother's widow, he has acquired her to wife, and he cannot give her a bill of divorce until he comes of age; he can contract uncleanness by [connexion with] a menstruant so that he conveys uncleanness to what is beneath him in like degrees as [he that has a flux conveys uncleanness] to what lies above him; he can render [a woman] unqualified^I5 but he cannot render [a woman] qualified^I6 to eat of Heave-offering; he can render cattle invalid for the Altar;^I7 and a beast can be stoned^I8 because of him; and if he has connexion with any of the forbidden degrees prescribed in the Law they are put to death on his account, but he is not culpable.

I If she suffers a flow.
2 If she had passed her first seven days in the uncleanness of a menstruant, and then suffered flows on the next three consecutive days.
3 If he lived within the lifetime of his childless brother (cf. Yeb. 2¹).
4 If he was born after the death of the father, and then died, the mother is exempt from levirate marriage with her brother-in-law.
5 See p. 651, n. 5.
6 e.g. if his mother died he can inherit her goods, and if then he died his brothers by the same father (and another mother) inherit from him.
