כִּֽי־נֶ֣פֶשׁ כָּל־בָּשָׂ֗ר דָּמ֣וֹ בְנַפְשׁוֹ֮ הוּא֒ וָֽאֹמַר֙ לִבְנֵ֣י יִשְׂרָאֵ֔ל דַּ֥ם כָּל־בָּשָׂ֖ר לֹ֣א תֹאכֵ֑לוּ כִּ֣י נֶ֤פֶשׁ כָּל־בָּשָׂר֙ דָּמ֣וֹ הִ֔וא כָּל־אֹכְלָ֖יו יִכָּרֵֽת׃
Sapagkat ang buhay ng lahat ng laman ay ang dugo nito, ito ang kanyang buhay. At sinabi Ko sa mga anak ni Israel: Huwag kayong kakain ng dugo ng anumang laman, sapagkat ang buhay ng lahat ng laman ay ang dugo nito; sinumang kumain nito ay ihihiwalay.
Mishnah Keritot
If one ate blood of a slaughtered beast, a wild animal or a bird, either clean or unclean, or blood of an animal stabbed in his throat or neck, or of the blood of an animal slaughtered by having his throat ripped, or of the blood of the arteries whereby life-force escapes, he is liable. But [if he ate] the blood of the spleen or of the heart, or blood found in eggs, or blood of fish, or of locusts, or secondary blood, he is not liable. Rabbi Judah says: he is liable for secondary blood.
Mishnah Chullin
If a person slaughtered a hundred wild animals in one place, one covering suffices for all. If [he slaughtered] a hundred birds in one place, one covering suffices for all. If [he slaughtered] a wild animal and a bird in one place, one covering suffices for both. Rabbi Judah says: if he slaughtered a wild animal he should cover up its blood and then slaughter the bird [and cover it up also]. If a person slaughtered and did not cover up the blood and another person saw it, the other must cover it up. If he covered it up and it became uncovered, he need not cover it up again. If the wind covered it up, he must cover it up again.
