4. And he used to observe with wisdom up and down. Because he sinned, these faces diminished, the wisdom disappeared from him, and he was only concerned with his own bodily matters. And afterwards he begot sons from above and below - THAT IS, ABEL WAS FROM THE UPPER ASPECTS AND CAIN FROM THE LOWER - and neither of them inhabited the earth, SINCE NONE OF THEM LEFT ANY DESCENDANTS IN THE WORLD. Then he fathered a son, NAMELY SETH, and from him the world was planted. This has been explained.
4. וַהֲוָה מִסְתָּכַּל בְּחָכְמְתָא, לְעֵילָּא וְתַתָּא. כֵּיוָן דְּסָּרַח, אִתְמַעֲטוּ פַּרְצוּפִין, וְחָכְמְּתָא אִסְתָּלָקַת מִנֵּיהּ, וְלָא הֲוָה מִסְתָּכַל אֶלָּא בְּמִלֵי דְּגוּפֵיהּ. לְבָתַר אוֹלִיד בְּנִין מֵעִלָּאֵי וְתַתָּאֵי, וְלָא אִתְיָשָׁבוּ דָּא וְדָא בְּעָלְמָא, עַד דְּאוֹלִיד בַּר, וּמִנֵּיהּ אַשְׁתִּיל עָלְמָא, דְּאִקְרֵי שֵׁת, וְהָא אוּקְמוּהָ.
