הַנֹּגֵ֥עַ בְּמֵ֖ת לְכָל־נֶ֣פֶשׁ אָדָ֑ם וְטָמֵ֖א שִׁבְעַ֥ת יָמִֽים׃
דער װאָס רירט זיך אָן אָן אַ מת, אָן װאָסער עס איז טױטן לײַב פֿון אַ מענטשן, זאָל זײַן אומרײן זיבן טעג.
Mishneh Torah, Sabbath
We may not judge, nor perform chalitsah, nor perform levirate marriage nor betroth a woman, [as a] decree lest one write. And we do not consecrate, nor appraise nor dedicate, since it is like buying and selling. And we do not separate priestly tithes and tithes, as it is similar to one consecrating the fruits that he separated; and also because it is like he fixes them on Shabbat. And we do not tithe animals, [as a] decree lest he mark [it] with red dye. But one may consecrate his Pesach sacrifice or his holiday (chagigah) sacrifice on a holiday, as this is the commandment of the day. And in the same way that we do not consecrate, so too do we not sanctify purifying waters (from the red heifer).
