349. Rabbi Yehuda continued by saying, "And he begot in his own likeness after his image" (Beresheet 5:3). This indicates that his other sons, CAIN AND ABEL, were not after his likeness, but Seth was in his own likeness and after his image, both physically and spiritually. As Rabbi Shimon said, in the name of Rav Yeba Saba (the elder), Adam's other sons had been produced in defilement, through attachment to the serpent and its rider, who is Samael. Hence, they bore no resemblance to Adam. Even though Abel, unlike Cain, was from another side OF PURITY AND NOT FROM THE SIDE OF THE SERPENT, neither had the form of Adam. THEY BOTH LACKED THE CENTRAL COLUMN, WHICH IS THE FORM OF ADAM. ABEL WAS FROM THE RIGHT SIDE AND CAIN FROM THE LEFT. HENCE, THEY WERE NOT CREATED IN THE LIKENESS OF ADAM.
