Genesis 4

12 When you work the ground, it shall no longer yield to you its strength. You shall be a fugitive and a wanderer on the earth." 13 Cain said to the Lord, "My *ch. 19:15punishment is greater than I can bear.*4:13 Or My guilt is too great to bear14 Behold, *Job 15:20-24you have driven me today away from the ground, and *2 Kgs. 24:20;Ps. 51:11;143:7;Jer. 52:3from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, *ch. 9:6;Num. 35:19and whoever finds me will kill me." 15 Then the Lord said to him, "Not so! If anyone kills Cain, vengeance shall be taken on him *Ps. 79:12sevenfold." And the Lord*[Ezek. 9:4,6;Rev. 14:9,11]put a mark on Cain, lest any who found him should attack him. 16 Then Cain went away from the presence of the Lord and settled in the land of Nod,*4:16 Nod means wandering east of Eden.
