כִּי֩ מִקְרֶ֨ה בְֽנֵי־הָאָדָ֜ם וּמִקְרֶ֣ה הַבְּהֵמָ֗ה וּמִקְרֶ֤ה אֶחָד֙ לָהֶ֔ם כְּמ֥וֹת זֶה֙ כֵּ֣ן מ֣וֹת זֶ֔ה וְר֥וּחַ אֶחָ֖ד לַכֹּ֑ל וּמוֹתַ֨ר הָאָדָ֤ם מִן־הַבְּהֵמָה֙ אָ֔יִן כִּ֥י הַכֹּ֖ל הָֽבֶל׃
For that which befalleth the sons of men befalleth beasts; even one thing befalleth them; as the one dieth, so dieth the other; yea, they have all one breath; so that man hath no pre-eminence above a beast; for all is vanity.
Read halakhic rulings (Jewish law) on Ecclesiastes 3:19: and classical halakhic sources.
