Genesis 4

12 When thou shalt work the earth, it shall not give his fruits to thee; thou shalt be unstable of dwelling, and fleeing about on [the] earth, in all the days of thy life.

13 And Cain said to the Lord, My wickedness is more than that I deserve forgiveness;

14 lo! today thou castest me out from the face of the earth; and I shall be hid from thy face, and I shall be unstable of dwelling, and fleeing about in earth; therefore each man that shall find me shall slay me.

15 And the Lord said to him, It shall not be done so, but each man that shall slay Cain shall be punished sevenfold. And the Lord set a sign in Cain, that each man that should find him should not slay him.

16 And Cain went out from the face of the Lord, and dwelled fleeing about in [the] earth, at the east coast of Eden, that is, of earthly paradise.
