וַיֹּ֧אמֶר ל֣וֹ יְהוָ֗ה לָכֵן֙ כָּל־הֹרֵ֣ג קַ֔יִן שִׁבְעָתַ֖יִם יֻקָּ֑ם וַיָּ֨שֶׂם יְהוָ֤ה לְקַ֙יִן֙ א֔וֹת לְבִלְתִּ֥י הַכּוֹת־אֹת֖וֹ כָּל־מֹצְאֽוֹ׃
O SENHOR, porém, lhe disse: Portanto quem matar a Caim, sete vezes sobre ele cairá a vingança. E pôs o SENHOR um sinal em Caim, para que não o ferisse quem quer que o encontrasse.

And the Lord said unto him, "Therefore whosoever slayeth Cain, vengence shall be taken on him sevenfold" (Genesis 4:15). R. Nehemiah said, "The punishment of Cain is not as the punishment of other murderers. Cain killed but he had none from whom to learn [the enormity of his crime]. [But] henceforth whosoever slayeth Cain shall be slain."
