Gen 4:12-22

12When you till the ground, it will no longer yield to you its strength; you will be a fugitive and a wanderer on the earth.”13Cain said to the Lord, “My punishment is greater than I can bear!14Today you have driven me away from the soil, and I shall be hidden from your face; I shall be a fugitive and a wanderer on the earth, and anyone who meets me may kill me.”15Then the Lord said to him, “Not so! Whoever kills Cain will suffer a sevenfold vengeance.” And the Lord put a mark on Cain, so that no one who came upon him would kill him.16Then Cain went away from the presence of the Lord, and settled in the land of Nod, east of Eden.Beginnings of Civilization 17Cain knew his wife, and she conceived and bore Enoch; and he built a city, and named it Enoch after his son Enoch.18To Enoch was born Irad; and Irad was the father of Mehujael, and Mehujael the father of Methushael, and Methushael the father of Lamech.19Lamech took two wives; the name of the one was Adah, and the name of the other Zillah.20Adah bore Jabal; he was the ancestor of those who live in tents and have livestock.21His brother's name was Jubal; he was the ancestor of all those who play the lyre and pipe.22Zillah bore Tubal-cain, who made all kinds of bronze and iron tools. The sister of Tubal-cain was Naamah.
