Bechoros7: 6
הַמַּקִּישׁ בְּקַרְסֻלָּיו, וּבְאַרְכּוּבוֹתָיו, וּבַעַל פִּקָּה, וְהָעִקֵּל. אֵיזֶהוּ עִקֵּל? כָּל שֶׁמַּקִּיף פַּרְסוֹתָיו, וְאֵין אַרְכּוּבוֹתָיו נוֹשְׁקוֹת זוֹ לָזוֹ. פִּיקָה יוֹצְאָה מִגּוּדָלוֹ, עֲקֵבוֹ יוֹצֵא לַאֲחוֹרָיו, פַּרְסָתוֹ רְחָבָה כְּשֶׁל אַוָּז, אֶצְבְּעוֹתָיו מֻרְכָּבוֹת זוֹ עַל זוֹ, אוֹ קְלוּטוֹת: עַד הַפֶּרֶק — כָּשֵׁר; לְמַטָּה מִן הַפֶּרֶק וַחֲתָכָהּ — כָּשֵׁר. הָיְתָה בוֹ יְתֶרֶת, וַחֲתָכָהּ: אִם יֶשׁ בָּהּ עֶצֶם — פָּסוּל; וְאִם לָאו — כָּשֵׁר. יָתֵר בְּיָדָיו וּבְרַגְלָיו, שֵׁשׁ וָשֵׁשׁ עֶשְׂרִים וְאַרְבַּע — רַבִּי יְהוּדָה מַכְשִׁיר, וַחֲכָמִים פּוֹסְלִים. הַשּׁוֹלֵט בִּשְׁתֵּי יָדָיו — רַבִּי פּוֹסֵל, וַחֲכָמִים מַכְשִׁירִים. הַכּוּשִׁי, וְהַגִּיחוֹר, וְהַלַּבְקָן, וְהַקִּפֵּחַ, וְהַנַּנָּס, וְהַחֵרֵשׁ, וְהַשּׁוֹטֶה, וְהַשִּׁכּוֹר, וּבַעֲלֵי נְגָעִים טְהוֹרִין — פְּסוּלִין בָּאָדָם, וּכְשֵׁרִין בַּבְּהֵמָה. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר: שׁוֹטָה בַבְּהֵמָה אֵינָהּ מִן הַמֻּבְחָר. רַבִּי אֱלִיעֶזֶר אוֹמֵר: אַף בַּעֲלֵי דִלְדּוּלִין פְּסוּלִין בָּאָדָם וּכְשֵׁרִין בַּבְּהֵמָה.
One who is bowlegged, or knock-kneed, or one who has a pikkah, or who is an ikkel. Who is an ikkel? Anyone who draws his feet together, and his knees do not touch each other. [One who has] a lump growing out of his thumb, [or] his heel protrudes backward, [or] his sole is wide like that of a goose, [or] his fingers lie one upon the other, or they are grown together [is unfit] —- [if it is only] until the joint, he is fit; [if it was] below the joint and he separated it, he is fit. [If] he had an additional [digit], and he amputated it: If it has a bone, he is unfit; if not, he is fit. [If he had] an additional digit on his hands and feet, six each, totaling twenty-four —- R’ Yehudah declares him fit, and the Sages declare him unfit. One [who] is ambidextrous —- Rabbi declares him unfit, and the Sages declare him fit. [If] he is black-skinned, or red-skinned, or an albino, or lanky, or a dwarf, or a deaf person, or a mental incompetent, or a drunk, or those afflicted with negaim that are adjudged tahor —- these are unfit in men, but fit in animals. Rabban Shimon ben Gamliel says: An animal that is mentally deficient is not [an offering] of choice. R’ Eliezer says: Also those with dangling flesh are unfit in man but fit in animals.
Bechoros7: 7
אֵלּוּ כְּשֵׁרִין בָּאָדָם, וּפְסוּלִין בַּבְּהֵמָה: אוֹתוֹ וְאֶת בְּנוֹ, וּטְרֵפָה, וְיוֹצֵא דֹפֶן, וְשֶׁנֶּעֶבְדָה בָהֶן עֲבֵרָה, וְשֶׁהֵמִית אֶת הָאָדָם. הַנּוֹשֵׂא נָשִׁים בַּעֲבֵרָה — פָּסוּל, עַד שֶׁיַּדִּיר הֲנָיָה. הַמִּטַּמֵּא לְמֵתִים — פָּסוּל, עַד שֶׁיְּקַבֵּל עָלָיו שֶׁלֹּא יְהֵא מִטַּמֵּא לְמֵתִים.
These are fit in man but unfit in animals: A father and son, a tereifah, one delivered by Caesarean section, one with whom a sin has been committed, or one that has killed a person. One who marries forbidden women is unfit, until he pronounces a vow pro-hibiting him from deriving benefit [from them]. One who contaminates himself with [the tumah of] dead bodies is unfit, until he pledges not to contaminate himself with [the tumah of] dead bodies.
