Genesis 4
4 Ref And Abel gave an offering of the young lambs of his flock and of their fat. And the Lord was pleased with Abel's offering;
5 Ref But in Cain and his offering he had no pleasure. And Cain was angry and his face became sad.
6 Ref And the Lord said to Cain, Why are you angry? and why is your face sad?
7 Ref If you do well, will you not have honour? and if you do wrong, sin is waiting at the door, desiring to have you, but do not let it be your master.
8 Ref And Cain said to his brother, Let us go into the field: and when they were in the field, Cain made an attack on his brother Abel and put him to death.
9 Ref And the Lord said to Cain, Where is your brother Abel? And he said, I have no idea: am I my brother's keeper?
10 Ref And he said, What have you done? the voice of your brother's blood is crying to me from the earth.
11 Ref And now you are cursed from the earth, whose mouth is open to take your brother's blood from your hand;
12 Ref No longer will the earth give you her fruit as the reward of your work; you will be a wanderer in flight over the earth.
13 Ref And Cain said, My punishment is greater than my strength.
14 Ref You have sent me out this day from the face of the earth and from before your face; I will be a wanderer in flight over the earth, and whoever sees me will put me to death.
15 Ref And the Lord said, Truly, if Cain is put to death, seven lives will be taken for his. And the Lord put a mark on Cain so that no one might put him to death.
