וַיֹּ֧אמֶר ל֣וֹ יְהוָ֗ה לָכֵן֙ כָּל־הֹרֵ֣ג קַ֔יִן שִׁבְעָתַ֖יִם יֻקָּ֑ם וַיָּ֨שֶׂם יְהוָ֤ה לְקַ֙יִן֙ א֔וֹת לְבִלְתִּ֥י הַכּוֹת־אֹת֖וֹ כָּל־מֹצְאֽוֹ׃
Lalu Yang Mahakekal berfirman kepadanya, “Karena itu, siapa pun yang membunuh Kain…! Pembalasan atas Kain baru akan dijatuhkan setelah tujuh keturunan.” Lalu Yang Mahakekal memberikan suatu tanda kepada Kain, supaya siapa pun yang menjumpainya tidak menyerangnya.
On Flight and Finding
[60] On the other hand, of Cain the accursed fratricide’s death no mention is found anywhere in the Books of the Law—nay, there is an oracle uttered concerning him which says, “The Lord God set a sign on Cain, even this, that no man that found him should kill him” (Gen. 4:15).
The Midrash of Philo
Why whoever should slay Cain should be liable to bear a sevenfold punishment? (Genesis 4:15).
That the Worse is wont to Attack the Better
[166] For it is an almost invariable rule that both persons and causes are cherished by those who are friendly and attached to them, but brought to ruin by those who have nothing in common with them, and look on them with no favour. For this cause the sacred utterance, testifying in opposition to the feigned simplicity of Cain, says ‘ “Not so” are you minded as your words run’ (Gen. 4:15); for you say that everyone that has found your artifices in the wrestling-bout of words will kill you, but you know that not everyone will do so, since countless numbers have been enrolled on your side, and only he will do so who is a friend of virtue, but to you an irreconcilable enemy.
