Genesis 4:12-15

CAB(i) 12 When you till the earth, then it shall not continue to give its strength to you: you shall be groaning and trembling on the earth. 13 And Cain said to the Lord God, My crime is too great for me to be forgiven. 14 If You cast me out this day from the face of the earth, and I shall be hidden from Your presence, and I shall be groaning and trembling upon the earth, then it will be that anyone that finds me shall kill me. 15 And the Lord God said to him, Not so, anyone that slays Cain shall suffer a seven-fold vengeance; and the Lord God set a mark upon Cain, so that no one that found him would kill him.
