Commentaire sur La Genèse 4:25

וידע אדם AND ADAM KNEW — Lamech came to Adam Harishon, complaining about his wives. He (Adam) said to them: “Is it for you to be overparticular regarding God’s decrees? You do your duty, and He will do His!” They replied to him: “First correct yourself: have you not lived apart from your wife these 130 years, ever since, through you, death was decreed as a punishment?” At once ‘וידע אדם עוד וגו “Adam knew his wife עוד ” — What signifies the word עוד? It is used here to teach that his love for her was now greater than before (Genesis Rabbah 23:4-5).

וידע אדם עוד את אשתו, this occurred 130 years later than the last time, as is evident from 5,3. During the intervening years Adam had not sired any children because Chavah had been the cause of his being punished. He had kept his distance from her during all these years.
