Cain and Abel
Adam and Eve gave birth to Cain and Abel. Cain tilled the soils, while Abel was a shepherd. Both the brothers made sacrifices to God.
They gave the best of their produce to Him. Cain offered the veggies from his farm, and Abel tithed the first of all his animals. Abel was so concerned over this as he wanted to give the best.
God was pleased with Abel's offerings, but with Cain's. So Cain was so jealous about this.
So Cain killed his brother. God asked him about his brother. He replied, "I don't know. Am I his keeper".
God became angry on him and made him as a wanderer of the Earth. Cain feared that anyone could kill him. But God put a mark on him as no man can do any harm.
From then he had to live his rest of his life feeling guilty of what he has done to his brother.
