וַֽיְחִ֥י קֵינָ֖ן שִׁבְעִ֣ים שָׁנָ֑ה וַיּ֖וֹלֶד אֶת־מַֽהֲלַלְאֵֽל׃
Kenan hidup tujuh puluh tahun, lalu ia memperanakkan Mahalaleel.
Midrash BeChiddush
לְעֹ֘שֵׂ֤ה נִפְלָא֣וֹת גְּדֹל֣וֹת לְבַדּ֑וֹ “Who alone works great marvels” (Ps. 136:4) This was the generation of Kenan. (Gen 5:12) In the D”H323D”H is most likely Divrei Hayamim, the book of Chronicles, though I am uncertain about this. Chronicles lists the genealogy of the generations but says nothing more about the individuals who are listed, it states that Ada and Tzilah, the wives of Lamekh,324See Rashi on Genesis 4:16 - it was the custom of that generation to take two wives, one for bearing children and the other for pleasure…. See Bereshit Rabbah 23:2 were the daughters of Kenan. In Lamekh’s generation men began giving their wives a sterility potion so that they wouldn’t get pregnant and so their beauty would not be diminished. Rashi gives a reason for the names Ada and Tzilah. Tzilah was so called because she sat in the shadow of an adorned house like a bride while Ada was wrapped in a cloak like a mourner who was about to give birth.
It is well known that the Holy one does not give the key to childbirth over to human beings.325See BT Ta’anit 2a, Though Rabbi Foa lists the reference to the first chapter of Rosh Hashanah. Even though Tzilah was barren because of the infertility potion which Lamekh gave her, still she gave birth to a child. That is why it states, “As for Zillah, she gave birth….” (Gen 4:22) even though she was incapable. With regard to this Scripture states, “Who alone works great marvels” (Ps. 136:4) for God visits the barren.

Rashi
המול ימול יליד ביתך HE THAT IS BORN IN THY HOUSE MUST NEEDS BE CIRCUMCISED — Here the statement that one born in the house must be circumcised is repeated but it does not say “after eight days” as in 5:12, thus teaching you that there are some cases of those “born in the house” who have to be circumcised on the first day of birth, as is explained in Treatise Sabbath (Shabbat 135b).
Rashi
את הימים means THE MULES — He crossed an ass and a mare, the offspring being a mule. Being himself the offspring of an unnatural union he reared such in the animal world (Pesachim 54a). Why are they called ימים (which may signify “dreaded beings”)? Because the fear of them lies upon people; for R. Hanina said, “No-one has ever consulted me about an injury caused by a white mule and has recovered (וחיה literally, lived)”. “But do we not see that such a person has recovered (lived)? But you should not read וחיה “and he lived”, but וחיתה “and it (the wound) healed up” — for such a wound never heals up (Chullin 7b). From “But do we not see" is to be found in an old text of Rashi. It would have been unnecessary to write the genealogy of the Horites had it not been that it wishes to mention Timna, thereby showing in what importance Abraham was held, as I have explained above (Genesis 5:12).
