3 When Adam had lived 130 years, he begot a son in his likeness after his image, and named him Shet.

5:3 In his likeness after his image
Rabbi Yehuda Halevi, a medieval poet and philosopher who lived in Spain and later Jerusalem, states in his work The Kuzari that Cain killed Abel because he thought that Abel would inherit the Land of Israel and continue Adam’s lineage. When Shet was born in the likeness of Adam, he replaced Abel, and, therefore, became fitting to inherit the land in Adam’s stead. From the onset of history, Eretz Yisrael has been recognized as unique and chosen, and since then, many have sought to inherit it at all costs.
