הֵן֩ גֵּרַ֨שְׁתָּ אֹתִ֜י הַיּ֗וֹם מֵעַל֙ פְּנֵ֣י הָֽאֲדָמָ֔ה וּמִפָּנֶ֖יךָ אֶסָּתֵ֑ר וְהָיִ֜יתִי נָ֤ע וָנָד֙ בָּאָ֔רֶץ וְהָיָ֥ה כָל־מֹצְאִ֖י יַֽהַרְגֵֽנִי׃
Ты изгоняешь меня сегодня с земли. Я буду скрыт от Твоего внимания, стану скитальцем и странником, и каждый встречный сможет меня убить!
Chizkuni
והיה כל מוצאי, וגו, “and anyone who will encounter me (in my exile will feel free to kill me;”) I will not even be able to atone while in exile.
Sforno
והיה כל מוצאי יהרגני, the fact that anyone who finds me is legally entitled to kill me makes my punishment much more severe than You, G’d, have told me.
Kitzur Ba'al HaTurim
The word "מוצאי" in Genesis 4:14 means "my banishment" or "my exile". In the Talmudic interpretation, it is explained as "For the righteous, [God] showed them the place of their burial, but for the wicked, he did not; rather, it is said of them: 'my exile is too great to bear'." This is why the sages said to those on the right, "Hold the cup of life," and to those on the left, "Hold the cup of suffering." This is the meaning of the verse "whoever finds me will kill me."
