At harvesttime Cain brought to the LORD a gift of his farm produce,
while Abel brought several choice lambs from the best of his flock. The LORD accepted Abel and his offering,
but he did not accept Cain and his offering. This made Cain very angry and dejected.
"Why are you so angry?" the LORD asked him. "Why do you look so dejected?
You will be accepted if you respond in the right way. But if you refuse to respond correctly, then watch out! Sin is waiting to attack and destroy you, and you must subdue it."

But the LORD said, "What have you done? Listen -- your brother's blood cries out to me from the ground!
You are hereby banished from the ground you have defiled with your brother's blood.
No longer will it yield abundant crops for you, no matter how hard you work! From now on you will be a homeless fugitive on the earth, constantly wandering from place to place."
Cain replied to the LORD, "My punishment is too great for me to bear!
