Tafsiran Kejadian 5:3: Rashi, Chizkuni, Ramban & Sforno

שלשים ומאת שנה A HUNDRED AND THIRTY YEARS — Until then he lived apart from his wife (Genesis Rabbah 24:6).

ויולד בדמותו כצלמו, “he begot a son in his likeness in his image;” the emphasis on this is to show us that anything he begot during the previous 129 years were only creatures that did not reflect his likeness or image, i.e. disembodied spirits, mostly מזיקים, injurious, destructive spirits. (Compare 3,20)

AND HE BEGOT A SON IN HIS OWN LIKENESS, AFTER HIS IMAGE. It is known that all who are born from the living are in the likeness and in the image of those who give birth to them, [so why was this verse necessary?] However, because Adam was elevated in his likeness and image in that Scripture said of him, In the likeness of G-d He made him,⁴⁷⁶Verse 1. Scripture explains that his offspring were also in this ennobled likeness. Scripture did not state this concerning Cain and Abel for it did not want to prolong the discussion of them. It explains it, however, in the case of Seth because the world was founded from him, [Noah being his direct descendant]. Or it may be that because Adam was created with absolutely perfect form, Scripture relates concerning Seth that he was like him [Adam] in strength and beauty.
