Genesis 4:3-10

3One day, it was time for the harvest. Cain brought to the Lord some of his crops as an offering.

4But Abel brought to God some of the first lambs that his sheep had given birth to. He brought pieces of fat from the best of his lambs to offer them to God. Abel and his gift pleased the Lord.

5But God was not pleased with Cain and his gift. So Cain became very angry. His face looked sad.

6Then the Lord said to Cain, ‘Why are you angry? Why do you look sad?

7If you do what is right, I will accept you. But if you do not do the right thing, sin will be very near to you. It will be like a wild animal at your door that is ready to eat you. But you must become its master.’

8One day Cain said to his brother Abel, ‘We should go out to the fields.’ While they were in the fields, Cain attacked his brother Abel. He killed Abel.

9Then the Lord said to Cain, ‘Where is Abel, your brother?’ Cain replied, ‘I do not know where he is. Must I always keep my brother safe?’

10Then the Lord God said, ‘Why have you done this bad thing? Now your brother's blood is lying there on the ground. That is like his voice which is shouting to me for help.
