Bereshis 4:15-17

Orthodox Jewish Bible

¹⁵ And Hashem said unto him, Therefore whoever killeth Kayin, vengeance shall be taken on him sevenfold. And Hashem placed an ot (mark) upon Kayin, so that none finding him should kill him.

¹⁶ And Kayin went out from the presence of Hashem, and dwelt in Eretz Nod, east of Eden.

¹⁷ And Kayin knew his isha; and she conceived, and bore Chanokh (Enoch); and he built an ir (city), and called the shem of the ir, after the shem beno, Chanokh (Enoch).
