Genesis 4:16

הֵן גֵּרַשְׁתָּ אֹתִי הַיּוֹם מֵעַל פְּנֵי הָֽאֲדָמָה וּמִפָּנֶיךָ אֶסָּתֵר וְהָיִיתִי נָע וָנָד בָּאָרֶץ וְהָיָה כָל־מֹצְאִי יַֽהַרְגֵֽנִי

Behold, Thou hast driven me out this day from the face of the land; and from Thy face shall I be hid; and I shall be a fugitive and a wanderer in the earth; and it will come to pass, that whosoever findeth me will slay me.’

וַיֹּאמֶר לוֹ יְהוָה לָכֵן כָּל־הֹרֵג קַיִן שִׁבְעָתַיִם יֻקָּם וַיָּשֶׂם יְהוָה לְקַיִן אוֹת לְבִלְתִּי הַכּוֹת־אֹתוֹ כָּל־מֹצְאֽוֹ

And the LORD said unto him: ‘Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold.’ And the LORD set a sign for Cain, lest any finding him should smite him.

וַיֵּדַע קַיִן אֶת־אִשְׁתּוֹ וַתַּהַר וַתֵּלֶד אֶת־חֲנוֹךְ וַֽיְהִי בֹּנֶה עִיר וַיִּקְרָא שֵׁם הָעִיר כְּשֵׁם בְּנוֹ חֲנֽוֹךְ

And Cain knew his wife; and she conceived, and bore Enoch; and he builded a city, and called the name of the city after the name of his son Enoch.

וַיִּוָּלֵד לַֽחֲנוֹךְ אֶת־עִירָד וְעִירָד יָלַד אֶת־מְחֽוּיָאֵל וּמְחִיּיָאֵל יָלַד אֶת־מְתוּשָׁאֵל וּמְתוּשָׁאֵל יָלַד אֶת־לָֽמֶךְ

And unto Enoch was born Irad; and Irad begot Mehujael; and Mehujael begot Methushael; and Methushael begot Lamech.
