You are placed under a curse and can no longer farm the soil. It has soaked up your brother's blood as if it had opened its mouth to receive it when you killed him.
Then the Lord God said to the snake, “You will be punished for this; you alone of all the animals must bear this curse: From now on you will crawl on your belly, and you will have to eat dust as long as you live.
The Lord is coming from his heavenly dwelling place to punish the people of the earth for their sins. The murders that were secretly committed on the earth will be revealed, and the ground will no longer hide those who have been killed.
Those who depend on obeying the Law live under a curse. For the scripture says, “Whoever does not always obey everything that is written in the book of the Law is under God's curse!”
