כִּ֣י לִי֮ כָּל־בְּכוֹר֒ בְּיוֹם֩ הַכֹּתִ֨י כָל־בְּכ֜וֹר בְּאֶ֣רֶץ מִצְרַ֗יִם הִקְדַּ֨שְׁתִּי לִ֤י כָל־בְּכוֹר֙ בְּיִשְׂרָאֵ֔ל מֵאָדָ֖ם עַד־בְּהֵמָ֑ה לִ֥י יִהְי֖וּ אֲנִ֥י יְהוָֽה׃ (ס)
Porque meu é todo primogênito; no dia em que feri a todo primogênito na terra de Mitzrayim, eu santifiquei para mim todo primogênito em Yisrael, tanto de homem quanto de animal; eles serão meus, Eu sou o Eterno. {פ}
