Берешит 7:22 Галаха: Mishneh Torah, Sabbath

כֹּ֡ל אֲשֶׁר֩ נִשְׁמַת־ר֨וּחַ חַיִּ֜ים בְּאַפָּ֗יו מִכֹּ֛ל אֲשֶׁ֥ר בֶּחָֽרָבָ֖ה מֵֽתוּ׃

все, в чьих ноздрях было дыхание духа жизни, что бы ни было на суше, умерли.

Mishneh Torah, Sabbath

[If] they checked to his nostrils and did not find any breath to him, they leave him there – as he is already dead. [If] they checked and found the [people] higher up dead, they should not say, “The [people] lower down have already died.” Rather, we excavate for all [of them], as it is possible in a rockslide that the higher one will die and the lower one be alive.
