נדה ה׳Niddah 5

Mishnah 3ג׳

תִּינוֹקֶת בַּת יוֹם אֶחָד, מִטַּמְּאָה בְנִדָּה. בַּת עֲשָׂרָה יָמִים, מִטַּמְּאָה בְזִיבָה. תִּינוֹק בֶּן יוֹם אֶחָד, מִטַּמֵּא בְזִיבָה, וּמִטַּמֵּא בִנְגָעִים, וּמִטַּמֵּא בִטְמֵא מֵת, וְזוֹקֵק לְיִבּוּם, וּפוֹטֵר מִן הַיִּבּוּם, וּמַאֲכִיל בַּתְּרוּמָה, וּפוֹסֵל מִן הַתְּרוּמָה, וְנוֹחֵל וּמַנְחִיל. וְהַהוֹרְגוֹ, חַיָּב. וַהֲרֵי הוּא לְאָבִיו וּלְאִמּוֹ וּלְכָל קְרוֹבָיו כְּחָתָן שָׁלֵם:

A baby girl one day old can become impure as a niddah. At ten days old she can become impure as a zavah [a female who has certain types of atypical genital discharges, distinct from her menses, which render her impure]. A baby boy one day old can become impure as a zav, or impure by having nega'im [diseased patches on skin, clothes, or houses that create impurity], or impure through [contact with] the impurity of a corpse; and he creates a bond for yibum [the obligation to perform Levirate marriage]; and he can exempt one from requiring yibum [i.e. if his father dies, he counts as a son to except any of his uncles from having to do yibum]; and he can feed terumah [i.e. his existence can render terumah permissible to one for whom it was formerly forbidden]; and he can render terumah to be forbidden [to one who was formerly permitted to eat it]; and he can inherit or cause others to inherit [portions of an estate]; and one who kills him is liable [for murder]; and he is thereby fully like a son-in-law to his father and to his mother and for all his relatives.

Mishnah 4ד׳

בַּת שָׁלשׁ שָׁנִים וְיוֹם אֶחָד, מִתְקַדֶּשֶׁת בְּבִיאָה. וְאִם בָּא עָלֶיהָ יָבָם, קְנָאָהּ. וְחַיָּבִין עָלֶיהָ מִשּׁוּם אֵשֶׁת אִישׁ, וּמְטַמְּאָה אֶת בּוֹעֲלָהּ לְטַמֵּא מִשְׁכָּב תַּחְתּוֹן כָּעֶלְיוֹן. נִשֵּׂאת לְכֹהֵן, תֹּאכַל בַּתְּרוּמָה. בָּא עָלֶיהָ אַחַד מִן הַפְּסוּלִים, פְּסָלָהּ מִן הַכְּהֻנָּה. בָּא עָלֶיהָ אַחַד מִכָּל הָעֲרָיוֹת הָאֲמוּרוֹת בַּתּוֹרָה, מוּמָתִין עַל יָדָהּ, וְהִיא פְטוּרָה. פָּחוֹת מִכָּן, כְּנוֹתֵן אֶצְבַּע בָּעָיִן:

A girl three years and one day old can become sanctified [for marriage, i.e. engaged] through intercourse; and if she had relations with a yavam [one obligated to perform leverite marriage], he has acquired her [as his wife]; and one is liable for [having relations with] a married woman on her account [if she is married]; and she renders one who sleeps with her impure [if she is a niddah] such that he renders impure that which he sits upon, the lower [layer of bedding, even if he does not touch it directly], just like the upper [layer of bedding]. If she marries a priest, she can eat terumah. If someone invalid [for the priesthood] had relations with her, she becomes invalid for the priesthood. If any one of the illicit relatives stated in the Torah had relations with her, they are put to death on her account, but she is exempt. If she is younger than that, it is like putting a finger in an eye.
