If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is contrary to you, but you must rule over it.”
Cain spoke to Abel his brother. And when they were in the field, Cain rose up against his brother Abel and killed him.
Then the LORD said to Cain, “Where is Abel your brother?” He said, “I do not know; am I my brother’s keeper?”
And the LORD said, “What have you done? The voice of your brother’s blood is crying to me from the ground.
And now you are cursed from the ground, which has opened its mouth to receive your brother’s blood from your hand.
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.”
Cain said to the LORD, “My punishment is greater than I can bear.
Behold, you have driven me today away from the ground, and from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, and whoever finds me will kill me.”
Then the LORD said to him, “Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold.” And the LORD put a mark on Cain, lest any who found him should attack him.
