כִּֽי־יִרְחַ֨ק מִמְּךָ֜ הַמָּק֗וֹם אֲשֶׁ֨ר יִבְחַ֜ר יְהוָ֣ה אֱלֹהֶיךָ֮ לָשׂ֣וּם שְׁמ֣וֹ שָׁם֒ וְזָבַחְתָּ֞ מִבְּקָרְךָ֣ וּמִצֹּֽאנְךָ֗ אֲשֶׁ֨ר נָתַ֤ן יְהוָה֙ לְךָ֔ כַּאֲשֶׁ֖ר צִוִּיתִ֑ךָ וְאָֽכַלְתָּ֙ בִּשְׁעָרֶ֔יךָ בְּכֹ֖ל אַוַּ֥ת נַפְשֶֽׁךָ׃
永恆者你的上帝所要選擇、要在那裡立祂名的地方，若離你太遠，你就可以照我所吩咐你的，從永恆者所賜給你的牛群和羊群中宰殺，在你的各城中隨心所欲地吃。
Mishnah Chullin
If he chopped off the head with one stroke, the slaughtering is invalid. He was slaughtering and he cut through the neck with one stroke, if the knife was as long as the neck, the slaughtering is valid. If he was slaughtering and he cut off two heads at the same time, if the knife is as long as the neck it is valid. When is this so? When the slaughterer moved the knife forward and not backward, or backward and not forward; but if he moved the knife to and fro, however small it was, even if it was a scalpel, the slaughtering is valid. If a knife fell down and slaughtered [an animal], even though it slaughtered it in the proper way, the slaughtering is invalid, for it is said, "And you shall slaughter and eat," that which you slaughter, you may eat. If [while slaughtering] the knife fell and he picked it up, if his clothes fell and he picked them up, if he sharpened the knife, or if he got tired and his friend came and [continued] slaughtering, if he delayed the time that it takes to slaughter, it is invalid. Rabbi Shimon says: if he delayed the time it takes to examine the slaughtering.
Mishnah Kiddushin
If he betroths [a woman] with orlah, or kilayim of the vineyard, or an ox condemned to be stoned, or the heifer whose neck is to be broken, or a leper’s bird-offerings, or a nazirite’s hair, or the first-born of a donkey, or meat [boiled] in milk, or non-sacred meat slaughtered in the Temple court, she is not betrothed. If he sells them and betroths [her] with the proceeds, she is betrothed.
