Cain and Abel were two of Adam and Eve’s sons. Cain was the oldest. Abel gave his whole heart to God and tried to follow God the best he could. He gave the best of his flock to God as a sacrifice since he was a shepherd. Cain was a farmer but he did not give his whole heart to God. He did not want to give God the best of his crop and did not like that God appreciated Abel’s sacrifices more. He was jealous. One day while Abel was tending to his flock, Cain came up and murdered him. Cain was the first murderer on the Earth. How would you like that name? Well, Abel also was the first to be murdered and to die. After Cain had killed Abel he decided to pretend he did not know where Abel was so when God came to him and asked where his brother was, Cain responded, “Am I my brother’s keeper?” in other words, “Am I responsible for my brother and do I have to look after him?” Cain, knowing what he had done and that everyone would soon know, was deeply afraid. He cried out that he would have to leave and that if anyone found him, he would surely be killed. God put a mark on the terrified Cain, that kept anyone from killing him. Cain ran away and left Adam and Eve with no son until they had Seth.
