רַ֥ק הַדָּ֖ם לֹ֣א תֹאכֵ֑לוּ עַל־הָאָ֥רֶץ תִּשְׁפְּכֶ֖נּוּ כַּמָּֽיִם׃
Seulement, vous n’en mangerez point le sang: tu le répandras sur la terre, comme de l’eau.
Mishnah Bikkurim
The blood of those who walk on two [legs] is like the blood of beasts in that it renders seeds susceptible [to impurity]. And it is like the blood of a sheretz, in that one is not liable for eating it.
