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).
